We introduce an approach of automatically identifying attacks by insider agents on dataflow-based processes having a collection-oriented data model and then improving the processes to prevent the attacks against them. Some process data, if used by some agents via steps at certain points of timeline, will lead to a privacy attack. A manual identification of these vulnerable data and rogue agents is...
We introduce Cyclone codes which are rateless erasure resilient codes. They combine Pair codes with Luby Transform (LT) codes by computing a code symbol from a random set of data symbols using bitwise XOR and cyclic shift operations. The number of data symbols is chosen according to the Robust Soliton distribution. XOR and cyclic shift operations establish a unitary commutative ring if data symbols...
A process is a collection of steps, carried out using data, by either human or automated agents, to achieve a specific goal. The agents in our process are insiders, they have access to different data and annotations on data moving in between the process steps. At various points in a process, they can carry out attacks on privacy and security of the process through their interactions with different...
