Abstract
Mobile device application access is managing by a hierarchical password protection mechanism. In this scheme, a set of passwords is configured in a hierarchy, wherein a password at a higher level in the hierarchy authorizes greater permissions than a password at a lower level in the hierarchy. Each password in the set of passwords is then associated with a respective application group of a set of application groups, each application group comprising applications having a common security requirement. Thus, a given password in the password hierarchy is associated with a particular application group. When the device detects entry of a given password at a given level in the hierarchy, access to the applications in the application group associated with the given password is then enabled automatically. In addition, access to the applications in each application group associated with passwords that are lower in the hierarchy also is enabled.
