In this article, an encryption algorithm with an error detection technique is presented for highly secured reliable data transmission over unreliable communication channels. In this algorithm, an input data is mapped into orthogonal code first. After that the code is encrypted with the help of Linear Feedback Shift Register (LFSR). The technique has been successfully verified and synthesized using Xilinx by Spartan-3E FPGA. The results show that the error detection rate has been increased to 100% by proposed encryption scheme is effective and improves bandwidth efficiency.

Error Detection Rate

AbstractQuality control of morphometric neuroimaging data is essential to improve reproducibility. Owing to the complexity of neuroimaging data and subsequently the interpretation of their results, visual inspection by trained raters is the most reliable way to perform quality control. Here, we present a protocol for visual quality control of the anatomical accuracy of FreeSurfer parcellations, based on an easy to use open source tool called VisualQC. We comprehensively evaluate its utility in terms of error detection rate and inter-rater reliability on two large multi-site datasets, and discuss site differences in error patterns. This evaluation shows that VisualQC is a practically viable protocol for community adoption.

To tackle such problems as low security, inefficiency and high cost in traditional data transmission between different security domains, this paper discussed the basic design decisions that form the first step one should consider, especially for creating a design with the advantage of high-efficiency and low-cost optical devices. It first explored the design issues of software and hardware systems with the application of various network separation systems. It then described the reliability features with regard to error detection and data integration, and the mechanism of the newly defined protocol structure. At last, it outlined the key design points for the system implement and measurement.
