Abstract: A system includes an authentication server and a media authentication device. The authentication server stores authenticated media files. The authenticated media files have an associated string value. Generally, the authentication device is used to scan a barcode on a media sample, determine a string value from the scanned barcode, generate a string value based on fragments of the media sample, and determine a string value from an authenticated media file on the authentication server. The authentication device then concatenates the barcode string value with the generated string value, and it concatenates the authentication string value with the generated string value. A hash function is applied to the concatenated string values, and the resulting hash values are compared. The authentication device causes to be displayed an indication that the media sample is authentic when the hash values match.

Abstract: An apparatus includes a memory and a hardware processor. The memory stores a first profile and a first hash. The processor receives a first message indicating that the user has entered a building and updates the first profile to produce a second profile. The processor generates a second hash, calculates a first deviation between the second hash and the first hash, and determines that the first deviation is below a threshold. The processor receives a second message indicating that the user has requested access to a software application and updates the second profile to produce a third profile. The processor also generates a third hash, calculates a second deviation between the third hash and the first hash, determines that the second deviation is above the threshold, and in response, flags the user for increased security monitoring and denies the user access to the software application.
