Techniques are disclosed for use in authentication. In one embodiment, a method is disclosed. The method comprises receiving an electronic request to access a computerized resource. The electronic request comprises a user identifier identifying a user associated with the electronic request and a first access token. The method comprises retrieving, in response to receiving the electronic request, a time-varying token seed associated with the generation of access tokens during a time period. The time-varying token seed is different if retrieved after the expiration of the time period. The method comprises generating a second access token based on the time-varying token seed and the user identifier identifying the user. The method comprises comparing the first and second access tokens to determine a similarity between the respective access tokens. The method comprises determining whether to allow the user access to the computerized resource based on the similarity between the access tokens.

Method, apparatus and computer program product for processing an electronic request to access a computerized resource

A technique controls access to a resource. The technique includes deriving, by processing circuitry, a password based on a phrase/thought provided by a user. The technique further includes confirming with the user that the password is to control access to the resource. The technique further includes, after confirming with the user that the password is to control access to the resource, imposing a requirement that the user provide the password before obtaining access to the resource. Such a password may be formed by concatenating multiple words (e.g., four words) that may be unrelated to each other. Such a password may be relatively strong since the resulting concatenation would not be found in any dictionary, and since it would be an extremely difficult and time consuming endeavor to predict such a password by attempting to combine words from a dictionary to form the concatenations.

Access control using passwords derived from phrases provided by users

Techniques are disclosed for verifying caller identification in voice communications. In one embodiment, there is disclosed a method comprising receiving a request to establish a voice call between communications devices. The request comprising encrypted information and an identifier identifying a caller associated with the request to establish the voice call. The method further comprises retrieving, in response to receiving the request, a decryption key from an authentication source by requesting from the authentication source the decryption key associated with the identifier. The method further comprises utilizing the decryption key to decrypt the encrypted information and produce decrypted information as well as comparing the decrypted information and the identifier to determine a similarity therebetween. The method further comprises providing, based on the comparison, an indication of whether or not the request is deemed associated with fraud.
