Encryption-compression of echographic images using FMT transform and DES algorithm
(Universidade Federal de Lavras (UFLA), 2007)
Read / Write Performance for low memory passive HF RFID tag-reader system
(Universidad de Talca, 2009)
Phase-only optical encryption based on the zeroth-order phase-contrast technique
(SPIE-SOC PHOTOPTICAL INSTRUMENTATION ENGINEERS, 2009)
A phase-only encryption/decryption scheme with the readout based on the zeroth-order phase-contrast technique (ZOPCT), without the use of a phase-changing plate on the Fourier plane of an optical system based on the 4f ...
Synchronized chaotic phase masks for encrypting and decrypting images
(ElsevierÁmsterdam, Países Bajos, 2019)
Optical encryption and QR codes: Secure and noise-free information retrieval
(Optical Society Of America, 2013-03)
We introduce for the first time the concept of an information “container” before a standard optical encrypting procedure. The “container” selected is a QR code which offers the main advantage of being tolerant to pollutant ...
Experimental QR code optical encryption: noise-free data recovering
(Optical Society Of America, 2014-05)
We report, to our knowledge for the first time, the experimental implementation of a quick response (QR) code as a “container” in an optical encryption system. A joint transform correlator architecture in an interferometric ...
Dynamic multiple-image encryption based on chirp z-transform
(IOP Publishing, 2019-02)
It is demonstrated a dynamic encryption scheme based on chirp − z transform (CZT). The novel design of this setup allows to protect multiple images in a multiplexed format and fully recover them without the influence of ...
