METHOD AND APPARATUS FOR USING A MULTI FACTOR PASSWORD OR A DYNAMIC PASSWORD FOR ENHANCED SECURITY ON A DEVICE

摘要

Techniques for improving security on a device are disclosed. In an aspect a multi factor password comprising a plurality of factors may be used to improve security. Each factor may correspond to a different type of information that may be used for authentication and/or other purposes. For example the plurality of factors may include an alpha numeric string a fingerprint of a user a voice clip a picture a video etc. The device may authenticate the user based on the multi factor password. In another aspect a dynamic password that varies with at least one parameter (e.g. time location etc.) may be used to improve security. The dynamic password may have a plurality of values for a plurality of scenarios defined by at least one parameter. The device may authenticate a user in a given scenario based on a value of the dynamic password applicable for that scenario.
