A Novel Approach for Data Encryption using ECG, SPIHT and Genetic Algorithm for Secured Applications

摘要

In today's computer world secured digital images are vulnerable to unauthorized access while in storage and during transmission over a network. Streaming digital images also requires high network bandwidth for transmission. In this paper we propose a new approach for data security using the concept of genetic algorithm and ECG with pseudo random binary sequence to encrypt and decrypt the data. To effectively utilize the bandwidth of the network image compression algorithm SPIHT is employed. The scope of this approach provides high data security and feasibility for practical implementation.
