After twenty years, a vulnerability in Lempel-Ziv-Oberhumer (LZO), an extremely efficient compression algorithm, has finally been patched. The flaw, a subtle integer overflow, existed for as long ...

The algorithm developed by Lempel and Ziv allows lossless compression, sans prior knowledge of the statistical properties of the data.

Ziv and Lempel co-invented the famous Lempel-Ziv algorithm that is the basis of ZIP files. Prof. Abraham Lempel died 7 weeks ago. On Sunday, March 26, 2023, Jacob Ziv, a prominent Israeli computer ...

He, alongside Professor Avraham Lempel, who died in February at the age of 86, developed the data compression algorithm Lempel-Ziv (LZ), which paved the way for the development of the ZIP, PDF ...
