A Modified Encryption Scheme in PEPSI Architecture to Prevent Collusion
With the proliferation of sensor-embedded mobile computing devices, democratic sensing is changing into common to gather data from and source tasks to taking part users. These applications take care of lots of non-public data, e.g., users' identities and locations at a particular time. Therefore, the authors like to pay a deeper attention to privacy and namelessness. However, from an information consumer's purpose of read, they wish to understand the supply of the sensing information, i.e., the identity of the sender, so as to judge what quantity the info is trusty. "Anonymity" and "Trust" area unit 2 conflicting objectives in democratic sensing networks and there aren't any existing analysis efforts that investigated the chance of achieving each of them at constant time.
