 Random number generators have limitations in terms of speed, entropy, seeding and bias, and security properties must be carefully analysed and measured to avoid predictability and compromise.With tokenization's increasing adoption, new tokenization technology approaches have emerged to remove such operational risks and complexities and to enable increased scale suited to emerging big data use cases and high performance transaction processing, especially in financial services and banking.Recent examples includes Protegrity's Vaultless Tokenization, Privitar Publisher tokenization, and Voltage Security's Secure Stateless Tokenization technology  and 's patented stateless tokenization solution SecurDPS.
