What is BER

Handbook of Research on Security Considerations in Cloud Computing
Short for bit error rate . In a digital transmission, BER is the percentage of bits with errors divided by the total number of bits that have been transmitted, received or processed over a given time period.

Nowadays data compression and authentication are believed to be vital to image transmission through heterogeneous infrastructure or storage at a centralized place. Though compression and authentication have independently grown to be matured technologies, but currently integration of these technologies is understood to be a key factor in handling tampering in images transmitted through unsecure channels like cloud. In this chapter, an error-resistant approach is investigated to add to low cost image authentication scheme to increase visual quality as well as improve author and user satisfaction. The image authentication includes content based digital signature that is watermarked and later diffused in the whole image before JPEG2000 coding. To tackle manipulations in the image, edge information of the image is examined to offset manipulations in the image transmission through noisy or open and unsecure channels. The edge image is sent along with JPEG2000 coded image to determine corrupted coefficients. The simulation results are conducted on test images for different values of bit error rate to judge confidence in error concealment within the received images.
