Abstract: This paper provides a novel method to improve the data storage of a quick response code (QR code) by applying encrypted lossless compression technology. QR codes are used in several domains, ...

It can be used to compress a single binary file, or it can operate on a list of files (or list of segments of a single file) so that several pieces of correlated data can be compressed together in a ...

Abstract: Choosing an appropriate division method is crucial for partitioning two-dimensional spatial data under the constraints of differential privacy. The current mainstream partitioning methods ...

In its traditional definition, an algorithm means a set of instructions that have been prepared beforehand to solve a particular problem. Algorithms could be an optimum simple procedure or a complex ...

One student’s desire to get out of a final exam led to the ubiquitous algorithm that shrinks data without sacrificing information. With more than 9 billion gigabytes of information traveling the ...
