Asymmetric cryptosystem based on optical scanning cryptography and elliptic curve algorithm https://share.newsbreak.com/1jyqtw88 - Open Access - Published: 11 May 2022 Asymmetric cryptosystem based on optical scanning cryptography and elliptic curve algorithm - Xiangyu Chang, - Wei Li, - … - Ting-Chung Poon Show authors Scientific Reports volume 12, Article number: 7722 (2022) Cite this article - 359 Accesses - Metricsdetails Abstract We propose an asymmetric cryptosystem based on optical scanning cryptography (OSC) and elliptic curve cryptography (ECC) algorithm. In the encryption stage of OSC, an object is encrypted to cosine and sine holograms by two pupil functions calculated via ECC algorithm from sender’s biometric image, which is sender’s private key. With the ECC algorithm, these holograms are encrypted to ciphertext, which is sent to the receiver. In the stage of decryption, the encrypted holograms can be decrypted by receiver’s biometric private key which is different from the sender’s private key. The approach is an asymmetric cryptosystem which solves the problem of the management and dispatch of keys in OSC and has more security strength than the conventional OSC. The feasibility of the proposed method has been convincingly verified by numerical and experiment results. Introduction Optical image encryption has attracted much attention in recent years because of its inherent capability of high parallelism and multidimensional freedoms (amplitude, phase and polarization). Since Refrégiér and Javidi first proposed the double random phase encoding (DRPE) technique1, researchers have introduced many extended optical encryption methods such as a series of optical transforms2,3,4,5, digital holography6,7,8, joint transform correlator9,10,11 and ghost imaging12,13,14, etc. Furthermore, optical scanning cryptography (OSC)15,16,17,18,19 envisioned by Poon has become a prospective technology. Different from that of other CCD-based hologram acquisition systems, it can capture the hologram of a physical object with a fast scanning mechanism along with single-pixel recording. Indeed, some encryption systems have been proposed based on OSC. Yan et al. obtained experimental results of encryption using fingerprint keys18. Furthermore, they first demonstrated optical cryptography of 3-D object images in an incoherent optical system with biometric keys19

I'm sensing a pattern here - the internet century apparently overtook ' The American Century " as far back as 2005! https://twitter.com/adam_tooze/status/1556241241490132994 TL/DR computer chips are a global concern and Japan and Germany prop up USG power. Caveat reposts etc

[spam][crazy][log] gdb, thread local, libgit, instruction pointet

I'm debugging a slowdown in my data generator for the adapters for semibalanced trees stuff. I have a lightweight c++ iterator to loop through repository references and to find which branch a random commit came from. The hang is happening inside the function that uses this iterator. I have a breakpoint set when a match is found. It extracts the name of the branch and stores it in a static thread local variable, a quick way to reuse heap allocation for dynamic strings. gdb is presently looping on this breakpoint, despite it being followed by a return statement.

[ot][spam][crazy] inhibition efforts: standing up

it takes me hours to reconnect to my body and stand up in the morning after sleeping. some years ago I searched for a device that would push me out of bed. somebody had made an "ejector bed" but they weren't selling it. I bought a cheap high-torque motor more recently. I don't know if it's strong enough to raise plywood with a person on it, but it seems to make sense to try. the motor also has a bracket to help with mounting, but more parts may be needed.

I am wearing an EEG headband, a Muse S. This is a very low quality consumer EEG device with 4 channels. I used to use two OpenBCI Cytons, with daisies, for a total of 8-32 channels. A cyton+daisy costs $2000 . I do not have income. I bought more than two. They break, for some reason. The software is designed with poor standards and the company has not been able to find a lead dev to hire. OpenBCI used to sell a direct current stimulator, too. When I began purchasing, they took it off the shelves, citing a research study that it was unhealthy or dangerous. I believe direct current stimulation is a way to entrain channels in the brain to observe areas not near the surface, and was very sad to not have access to the open source equipment once I had saved enough money to buy it.

Turkey chickens out of crypto-repression - goes running to Mummy Russia

Even in Turkey, where the democratic process does not function as intended, a strong government that controls all branches of the state decided not to pass a top-down bill to regulate cryptocurrencies due to community objections. https://www.coindesk.com/layer2/2022/08/03/lessons-from-the-turkish-governm… Reposts etc

158 highlights to DONALD J. TRUMP, vs. HILLARY R. CLINTON. Honestly, I understand the FBI's scenario here. Why on god's green Earth would New York be used and abused while at the expense of innovation.

A CPU world record has been broken by dousing a $6,000+ AMD chip in liquid nitrogen

A CPU world record has been broken by dousing a $6,000+ AMD chip in liquid nitrogen https://share.newsbreak.com/1juy5ego It's a shame that AMD's Threadripper processors are no longer in the reach of most enthusiast gamers because the AMD Ryzen Threadripper Pro 5995WX just crushed a Cinebench run to net itself the world record. Proving once again that AMD's mammoth chip is not to be trifled with. With a multithreaded score of 116,142 in Cinebench R23, overclocker TSAIK has net themselves the world number one spot (spotted by 9550pro on Twitter ), beating out user blueleader with two AMD Epyc 7763 server chips at 113,566.
