BA01 - Enriched Digital Diary

Visiting new places enthuses users to shoot photos.gq In addition to the pictures, users can record a voice narrative or even a video on those visited places. Users usually possess several devices, i.e., mobile phones, cameras, and other devices, which can be used to generate different kinds of digital content. Having generated diverse multimedia digital content that can be linked to a place or a specific activity, users require a helping tool that enables them to organize those generated multimedia content in one multimedia document. We will call this multimedia document "Digital Diary". It is expected from the device to perform some analysis tasks on the generated multimedia content to identify some subjects that those content encode. You can consider this analysis task as an added value for our tool. Once those encoded subjects are identified, the device retrieves additional data about the subjects from open linked data provided, e.g., DBpedia, and includes those retrieved data in the Digital Diary.

BA02 - Audio Narrated Digital Manual

  With the proliferation of mobile devices and applications that allow the users to take photos and record audio files that describe these photos, users become in need of tools that help them to organize their photos and the related audio files in professionally authored presentations. Linking an image with the most relevant part of an audio file that describes this image remains a non-trivial task for the users. This project aims at finding a solution for the related problem, i.e., an audio narrated digital manual.

BA04 - Implement a public blockchain system

  Some several frameworks and systems implement blockchain, e.g., Bitcoin, Ethereum, Multichain, and others. However, to grasp the technology and understand the main building blocks of blockchain technology, this project aims at implementing a blockchain system. You are expected to define the data model of the blocks, use the hashing algorithms, implement a function to create the Merkle Tree, implement a proof-of-work (PoW) algorithm, mine new blocks, execute transactions, and a simplified peer-to-peer (P2P) protocol.  


 

BA05 - Implement private blockchain system

  Some several frameworks and systems implement blockchain, e.g., Bitcoin, Ethereum, Multichain, and others. However, to grasp the technology and understand the main building blocks of blockchain technology, this project aims at implementing a blockchain system. You are expected to define the data model of the blocks, use the hashing algorithms, implement a function for creating the Merkle Tree, implement a proof-of-authority (PoA) algorithm, mine new blocks, execute transactions, and a simplified peer-to-peer (P2P) protocol.  


BA06 - Implement auction system for digital assets based on blockchain technology

  In a real-life scenario, auctions take place in dedicated public halls. An auctioneer offer goods or services to sell them; the bidder who bids the highest value for those goods and services wins. The goal of this project is to implement an auction system making use of one of the available blockchain systems. The system makes sure that the auctioneer owns the offered digital assets and the bidder has enough balance to cover her bid. By making use of smart contracts, the system should ensure that the bid transaction is executed correctly, i.e., the seller receives the values of the sold digital assets, and the buyer receives the ownership of what she bought.

BA07 - Semantic blockchain: Use of a rules engine to extract information from blocks.

Blockchain provides a reliable infrastructure for persisting read-only data. Besides the basic data model, i.e., block headers, which are required by blockchain to connect the blocks in a chain, blockchain technology allows storing and retrieving data encoded using custom data models.

This project aims to develop a generic solution for storing the data in graphs and make use of the graph theory to connect the pieces of the graphs which are stored in the blocks and extract new hidden information using the available reasoning methods.

Use-case scenario: Given a marketplace where artists (sellers) can offer digital multimedia resources for buyers, buyers can also re-sell those digital resources using the same marketplace. Both artists and buyers can - as owners only - edit the metadata of the digital resources. The blockchain system should track the changes made to the metadata, i.e., who, when, and what. Editing some metadata attributes such as the creator and creation date should be prohibited by the system. The system shall prohibit changing the original digital resource as well. In a later step, the system should provide interlinked data on artifacts, artists, buyers. The blockchain system allows reasoning over the stored data.

BA08 - Semantic blockchain: Adding Graph-Data Service-Layer to Ethereum

Blockchain provides a reliable infrastructure for persisting read-only data. Besides the basic data model, i.e., block headers, which are required by blockchain to connect the blocks in a chain, blockchain technology allows storing and retrieving data encoded using custom data models.

This project aims to find a solution for storing the data in graphs and make use of the graph theory to connect the pieces of the graphs which are stored in the blocks and extract new hidden information using the available reasoning methods. To be able to fulfill the requirements of this project, your solution can make use of the available platforms and frameworks, i.e., Ethereum, EthereumJ, GO language, Apache Jena, etc. In other words, it is not expected from you to implement a new blockchain system but to extend the functionalities of one of the open-source blockchain systems by adding a new graph-data service layer.

GQ01 – SAP Scenes – Extension for Cybersecurity

Following the paradigm “Every great experience starts with a great story”, SAP SCENES has revolutionized the way in which system design is approached. The idea also looks very promising for the field cybersecurity, where events (attacks and mitigating actions) often develop along a story line. The goal of this project is to develop a modelling tool and a set of resources that allow a system designer to “draw system defence stories”. These stories consist of episodes (scenes) and should primarily serve as basis for cyber exercise scenarios.

GQ02 – Cybersecurity situation analysis

Based on the phases of the famous OODA-Loop decision model, which is identified in the business and in the IT literature as an important paradigm shift, an observation and orientation tool support should be developed to enhance the analysis of attacks. This tool should therefore be focussed on providing input for the observation and orientation phases, which are also a major element in the NIST Cyber Security Framework, especially in the identification of attacks.

GQ03 – Emerging patterns in cybersecurity

The early identification of a cyber attack through indicators of compromise can be signature- or behaviour based. In both cases the problem is to pick up early signs of a developing attack without raising false alarms. Two prototypes are to be developed in this topic, one for each approach. The implemented prototypes should then be combined into a workbench that allows the combination of analysis results. The idea is that the probability of an attack being present is much higher if both sound an alarm. This should help with reducing false positives/alarms.

PK01 Ambient Home Messenger

An ambient device is a decorative type of consumer electronics that display information in a user’s environment and thereby require minimal mental effort from the user. To counteract the information overload, a stationary device called Ambient Home Messenger can record and play video and audio messages to people registered to the device.
The goal of the project is to design, assemble, and implement a device that is capable of recording and playing audio and video messages like a stationary answering machine. Thereby the device should recognize the person in front of the camera (using face recognition technology) and determine the receiver of the message (using speech recognition).

PK06 FactCheck - Semi-automatic Selection of Precision Metrics for fact comparison

FactCheck is a framework for detecting and resolving conflicting data on the Web. It establishes an entire fact comparison process that consists of data acquisition, data comparison, the presentation of comparison results, and comprehensive analysis functions. FactCheck is a leading research topic of our research group and bears challenges in many different aspects.

In FactCheck, the precision metric is in charge of comparing two fact values, which then results in a conflict or a non-conflict. Fact comparisons require a precisely targeted choice of precision metrics. Different application scenarios require the use of varying precision metrics. This topic aims to develop an algorithm and an interface that allows a self-learning and self-adoptive system that provides an appropriate precision metric in each case and learns from wrong applications.

WK01 - Jupyter Notebooks for Dedicated Interactive Content of Courses

Jupyter Notebooks allow for the creation and sharing of documents that contain live code, equations, visualizations, and narrative text. Jupyter Notebooks are a well-established and well-recognized tool in academia and education in general as well as in specific fields of research where it is important to provide for reproducibility of scientific results. Goal of the project is to develop dedicated Jupyter Notebooks for specific course content relevant in the context of our courses (MOD, MCM, MST, MRE, MRS). The approach can be based on the existing framework that we already use for Juypter Notebooks in some of our courses but may also further improve or suggest new solutions for the framework as such. The selection of the programming language to be used needs to meet the requirements of the course content, most probably Python, but - in fact - is very flexible as Jupyter Notebooks work with a variety of languages.
Mandatory requirement: Student must have understood the course content / material very well and should have passed the course already.

WK02 - FactCheck - Precision Metrics

FactCheck is a framework for the detection and resolution of conflicting structured data on the Web. The FactCheck framework is the result of ongoing research at our research group. One of the central building blocks is the context-dependent comparison of structured data of various representations of one and the same real world object or artefact. The comparison is guided by so called precision metrics which is a flexible and sophisticated technique for logically comparing structured data values. Precision metrics consist of logical predicates used to evaluate the comparison of structured data. Goal of the project is to design and implement an appropriate model for the representation of precision metrics, the construction of such precision metrics as well as the application of the metrics for evaluating the comparison of data values. Various precision metrics should be defined and compared using a test dataset of 900.000 entities. Results of the project are to be demonstrated by a running demo application.

WK03 - Demo of Blockchain Application Using Proof-of-Authority (Ethereum)

The CS Faculty operates the recently founded  BlockchainSci-Lab. For students the lab offers an environment to get familiar and work with state of the art systems and platforms to learn about blockchain technology and to design and implement blockchain applications by participating in dedicated projects. The goal of this project is the implementation of a demo application which illustrates the concept of proof-of-authority (in place of the very often used "proof-of-work" as, e.g., used in the Bitcoin Blockchain). For example, a possible application could be the implementation of the four-eyes principle (Vier-Augen-Prinzip) for officially approving documents by making use of two signers acting as proof-of-authorities. There are many other possible application scenarios feasible, e.g., the decision taking principles of a management board of an association or a company, board of managers, board of trustees or directors. The application scenario should be well-chosen in order to illustrate the general principle of proof-of-authority. It may be based on a generic, configurable implementation to show different variations of the proof-of-authority concept, e.g., 1 signer, 2 signers, N signers. The demo application has to be realized such that a short demonstration movie can be recorded, that will be published on the Lab's website.

The CS Faculty operates the recently founded  BlockchainSci-Lab. For students the lab offers an environment to get familiar and work with state of the art systems and platforms to learn about blockchain technology and to design and implement blockchain applications by participating in dedicated projects. The goal of this project is the implementation of a demo application which illustrates the concept of private permissioned blockchains. The possible demo application can be discussed in more detail; examples are the decision taking principles of a management board of an association or a company, board of managers, board of trustees or directors. It should be well-chosen in order to illustrate the general principle. The demo application has to be realized such that a short demonstration movie can be recorded, that will be published on the Lab's website.

The CS Faculty operates the recently founded BlockchainSci-Lab. For students the lab offers an environment to get familiar and work with state of the art systems and platforms to learn about blockchain technology and to design and implement blockchain applications by participating in dedicated projects. The goal of this project is to implement an application for a digital "Studienleistungs & Prüfungspass" (study performance & examination pass) based on blockchain technology. The pass will record the individual, required study achievments (like milestones, tests, etc.) during a course, the final grading of a course, and the collection of gradings of courses during the entire study (like a "Sammelzeugnis" currently used by the university). There are various stakeholders in this scenario: the students, the lectures of courses, and administration (like SPL). The implementation has to be realized based on MultiChain Blockchain technology, which provides managed permissions and allows for millions of assets on a blockchain, structured asset data, multiple key-value, time series or identity databases on a blockchain.  MultiChain Blockchain technology is one of the most promising implementations for private, managed blockchain systems.

The CS Faculty operates the recently founded BlockchainSci-Lab. For students the lab offers an environment to get familiar and work with state of the art systems and platforms to learn about blockchain technology and to design and implement blockchain applications by participating in dedicated projects. The goal of this project is - starting out from a given demo implementation - to implement an application for a digital "Studienleistungs & Prüfungspass" (study performance & examination pass) based on blockchain technology. The pass will record the individual, required study achievments (like milestones, tests, etc.) during a course, the final grading of a course, and the collection of gradings of courses during the entire study (like a "Sammelzeugnis" currently used by the university). There are various stakeholders in this scenario: the students, the lectures of courses, and administration (like SPL). The implementation has to be realized based on Ethereum Blockchain technology, which provides the concept of Smart Contracts. Ethereum Smart Contract  technology is one of the most promising implementations for smart behaviour of blockchain systems. The focus will be on the proper design and implementation of smart contracts to capture most of the functionality of the application.

WK07 - Securing Images and Videos by Applying Blockchain Technology

The CS Faculty operates the recently founded BlockchainSci-Lab. For students the lab offers an environment to get familiar and work with state of the art systems and platforms to learn about blockchain technology and to design and implement blockchain applications by participating in dedicated projects. The goal of this project is the design and the implementation of a framework based on blockchain technology that allows for the detection of manipulations in images and videos. Images or videos can be manipulated, e.g., persons (or other objects) can be added to or removed from an image, video frames (or sequences of video frames) can be added or removed from a video. Such a manipulation should be detected based on the storage of specific image encoding parts in a blockchain which allows to re-check the validity of an image encoding. E.g., essential macroblocks or portions of some macroblocks of a JPEG-encoded image could be stored in a blockchain such that it can be checked whether an image still consists of those macroblocks or includes manipulated macroblocks. The project will first have to select and specify the kind of manipulations to be considered in the scope of the project, then design an approach and a framework and implement a prototype and a demo application illustrating the approach, based on a specific blockchain platform that suits best the needs of the application.
