Aiming at the problems of low storage efficiency, small space, and poor stability traditional financial data systems, a dynamic secure system based on distributed decoding is designed. The uses cloud security service to store large number obtained from sensing layer achieve reasonable scheduling through constraint software function. In addition, computing scheme hierarchical coding proposed, in...

An efficient scheme for JPEG2000 SNR progressive decoding is proposed, which is capable of handling JPEG2000 compressed image data with SNR progressiveness. In order to avoid entropy decoding of the same compressed data more than once when decoding SNR progressive images, two techniques are introduced in our decoding scheme; reuse of intermediate decoding result and differential inverse discret...

This paper gives a new approach to decoding Hermite codes using the key equation, avoiding the use of majority voting. Our approach corrects up to (dmin − 1)/2 errors, and works up to some extent also beyond. We present an efficient implementation of our algorithm based on a Sugiyamatype iterative procedure for computing solutions of a key equation.
