ESBT: A Scalable and Deterministic Sequence CRDT for Distributed Collaborative Editing
Moulay Driss Mechaoui, Abdessamad Imine
Modern collaborative editing systems require efficient mechanisms for managing concurrent updates across distributed replicas. Sequence Conflict-free Replicated Data Types (CRDTs)…
Private Link Exchange over Social Graphs
Hiep H. Nguyen, Abdessamad Imine, Michael Rusinowitch
Currently, most of the online social networks (OSN) keep their data secret and in centralized manner. Researchers are allowed to crawl the underlying social graphs (and data) but w…
Detecting Communities under Differential Privacy
Hiep H. Nguyen, Abdessamad Imine, Michael Rusinowitch
Complex networks usually expose community structure with groups of nodes sharing many links with the other nodes in the same group and relatively few with the nodes of the rest. Th…
A Constraint-based Approach for Generating Transformation Patterns
Asma Cherif, Abdessamad Imine
Undoing operations is an indispensable feature for many collaborative applications, mainly collaborative editors. It provides the ability to restore a correct state of shared data…
Efficient Polling Protocol for Decentralized Social Networks
Bao-Thien Hoang, Abdessamad Imine
We address the polling problem in social networks where individuals collaborate to choose the most favorite choice amongst some options, without divulging their vote and publicly e…
Anonymizing Social Graphs via Uncertainty Semantics
Hiep H. Nguyen, Abdessamad Imine, Michaël Rusinowitch
Rather than anonymizing social graphs by generalizing them to super nodes/edges or adding/removing nodes and edges to satisfy given privacy parameters, recent methods exploit the s…
On Consistency of Operational Transformation Approach
Aurel Randolph, Hanifa Boucheneb, Abdessamad Imine +1
The Operational Transformation (OT) approach, used in many collaborative editors, allows a group of users to concurrently update replicas of a shared object and exchange their upda…
A General Approach for Securely Querying and Updating XML Data
Houari Mahfoud, Abdessamad Imine
Over the past years several works have proposed access control models for XML data where only read-access rights over non-recursive DTDs are considered. A few amount of works have…
Secure Querying of Recursive XML Views: A Standard XPath-based Technique
Houari Mahfoud, Abdessamad Imine
Most state-of-the art approaches for securing XML documents allow users to access data only through authorized views defined by annotating an XML grammar (e.g. DTD) with a collecti…
On Coordinating Collaborative Objects
Abdessamad Imine
A collaborative object represents a data type (such as a text document) designed to be shared by a group of dispersed users. The Operational Transformation (OT) is a coordination a…
Experiments in Model-Checking Optimistic Replication Algorithms
Hanifa Boucheneb, Abdessamad Imine
This paper describes a series of model-checking experiments to verify optimistic replication algorithms based on Operational Transformation (OT) approach used for supporting collab…
