Abstract: A technique communicates a password to a user. The technique involves receiving, by processing circuitry, a request for a password. The technique further involves generating, by the processing circuitry, a password in response to the request. The password includes a series of alphanumeric digits which contains at least one number and at least one letter. The technique further involves displaying, by the processing circuitry, the password on a display screen. Each number displayed on the display screen has a first visual characteristic, and each letter displayed on the display screen has a visual characteristic that is different from the first visual characteristic. Such a technique enables disambiguation of an alphanumeric security code to a user.

Abstract: Exemplary methods for deduplicating encrypted files are described herein. The exemplary methods include receiving a first encrypted data file from a remote source that is encrypted by a first security key. In one embodiment, the methods include transmitting to a remote security manager a first key identifier (ID) that is extracted from the first data file, the first key ID identifying the first security key. In one aspect of the invention, in response to receiving the first security key from the remote security manager based on the first key ID, decrypting the first data file using the first security key provided by the remote security manager. In at least one embodiment, the methods include deduplicating the decrypted first data file.
