Multiplicative weights update algorithms have been used extensively in designing iterative algorithms for many computational tasks. The core idea is to maintain a distribution over a set of experts and update this distribution in an online fashion based on the parameters of the underlying optimization problem. In this report, we study the behavior of a(More)
Proof-of-work (PoW) is a popular algorithmic tool used to enhance network security by imposing a computational cost on participating devices. Unfortunately, traditional PoW schemes require that correct devices perform computational work perpetually, even when the system is not under attack. We address this issue by designing a general PoW protocol that(More)
The iris pattern of human eye is considered to be unique and distinct that it plays an important role as reliable biometric system for authentication purposes. Iris recognition has become a challenging issue under varying lighting or contrast conditions and due to occlusions such as eyelashes. Therefore, in this paper we have proposed a novel technique for(More)
