One of the group's main activities involves distributed data mining. The GOLF framework developed earlier was extended with the capability to adapt to dynamically changing environments and concept drift. The basic idea behind this method is to maintain a fixed age distribution in the network among the models. Young models help in adapting to sudden changes, while older models represent stabilit...

Broadcast encryption schemes rely on a centralized authority to generate decryption keys for each user. It is observed that, when a broadcast encryption scheme is deployed for secret escrows, a dishonest dealer can read the escrowed secrets without leaving any witnesses. We present a new broadcast encryption paradigm referred to as fully distributed broadcast encryption (FDBE) without suffering...

Sequence comparison is a fundamental task in pattern matching. Its applications include file comparison, spelling correction, information retrieval, and computing (dis)similarities between biological sequences. A common scheme for sequence comparison is the longest common subsequence (LCS ) metric. This paper considers the fully incremental LCS computation problem as follows: For any strings A,...
