- Optical Encryption for Data Security
Introduction
Encryption is the transformation of data into a form
that is nearly impossible to read without the appropriate
key. for data security applications, optical systems
offer many degrees of freedom like phase, spatial frequency
and polarization, to encode the data more securely.
Opto-electronic encryption systems incorporating polarization
encoding and fractional Fourier plane encoding have
been developed. These systems are based on double random
phase encoding and polarization based XOR operation
encoding techniques. Efficient encryption and decryption
in view of blind decryption cases have been carried
out.
Salient features:
High speed data encryption and decryption. Enhanced
security. PC based user interface.
Prospective Users: Banking
industry, Telecommunications, Internet service, Data
security, Secure data storage.
Keywords: Data security,
