US Patent:

20220228976, Jul 21, 2022

Filed:

Nov 23, 2021

Appl. No.:

17/533510

Inventors:

- Healdsburg CA, US
Toan Huynh - Mountain View CA, US

International Classification:

G01N 21/33
G01N 33/49

Abstract:

Methods and devices are provided to provide clean signals even in the presence of spectral interference. At least some of these methods can be applied for cases when interfering signals are to be accounted for. These cases include, but are not limited to, hemolysis detection, icterus detection, and assays. They can be implemented in with data collected with spectrophotometers, instruments that can collect absorbance values at the few wavelengths of interest, and, in the case of the method based on background subtraction, simple imaging setups with only two filters (such as but not limited to narrow-band and wide-band) per absorption peak of interest.

International Classification:

H04L 29/06

Abstract:

Credentials and other sensitive strings can undergo automatic rotation before each transmission or storage of those credentials. String modification, which can utilize a key stretching algorithm, can be used to modify the credential before transmission. This can be for an initial sign up, a subsequent login, or another such action. A random number can be generated to determine the number of iterations for the key stretching algorithm to be applied. For subsequent actions, a new random number can be added to the prior iteration number in order to create a new string that can be generated using the previously utilized iteration number and the new random number, with only the new random number being transmitted with the modified credential string. This increases security, as the transmission itself cannot be used to recover the original plaintext credential if recovered.
