Automatic Composition of Services with Security Policies

Yannick Chevalier, Mohammed Anis Mekki, Michaël Rusinowitch
2008 2008 IEEE Congress on Services - Part I  
For the domain of security services (such as digital signing or timestamping) we propose a novel approach to automated composition of services based on their security policies.  ...  The resulting composed service can be verified automatically for ensuring that it cannot be subject to active attacks from intruders.  ...  We show how one can derive automatically a Digital Contract Signing service from components services.  ...

Blockchain protocols in clinical trials: Transparency and traceability of consent

Mehdi Benchoufi, Raphael Porcher, Philippe Ravaud
2017 F1000Research  
Clinical trial consent for protocols and their revisions should be transparent for patients and traceable for stakeholders.  ...  For each revision of the protocol, consent was sought again.  ...  For example, anyone with access to a consent form could create an unlimited number of bitcoin private keys and use these private keys to digitally sign the consent form.  ...

Connecting Bitcoin Blockchain with Digital Learning Chain Structure in Education

2019 Acta Polytechnica Hungarica  
In the DLCC blockchain, specifically, in the Smart Contract, the terms of contract are kept, concerning the bursaries, terms agreed by both parties (students and universities alike).  ...  In the present paper, an extension of the Bitcoin (BTC) structure is introduced, with a proprietary and unique DLCC (Digital Learning Chain Structure) blockchain, through which an automated bursary payment  ...  A transaction is formed by digitally signing a hash of the transaction through which a BTC was acquired.  ...

Watermarks and Text Transformations in Visual Document Authentication

Igor Fischer, Thorsten Herfet
2007 Journal of Computers  
Integrity of digital documents is a very important issue if they are to be legally binding.  ...  To prevent potential attackers from obtaining signatures without author's knowledge, we propose using a simple challenge-response protocol.  ...  Detecting tampering might not be sufficient for Alice to have her work done: If she needs to send a signed contract to Bob, she still won't be able to do it.  ...

Orchestration under Security Constraints [chapter]

Yannick Chevalier, Mohamed Anis Mekki, Michaël Rusinowitch
2011 Lecture Notes in Computer Science  
For the domain of secured services (using e.g. digital signing or timestamping) we propose a novel approach to automated composition of services based on their security policies.  ...  We have applied the AVANTSSAR Platform to a digital contract signing (DCS) case study, provided by OpenTrust. A Business Portal (BP) is provided to parties that plan to digitally sign a contract.  ...  We show how we can derive automatically a Digital Contract Signing service from their components services.  ...

Smart contracts that are smart and can function as legal contracts - A Review of Semantic Blockchain and Distributed Ledger Technologies [article]

Marcelle von Wendland
2018 arXiv   pre-print
One of the biggest challenges though is the level of support for semantics by most of the Block Chain and Distributed Ledger technologies.  ...  Blockchain and Distributed ledger Technologies are increasingly becoming key enablers for vital innovation in financial services, manufacturing, government and other industries.  ...  The term semantics as widely understood today refers to this process of creating of such digital protocols for getting certainty of meaning.  ...
