Digital assets are in a secured form that only those with granted access rights can access. Even with the proper access privilege, when a secured file is classified, at least a security clearance key is needed to ensure those who have the right security clearance can ultimately access the contents in the classified secured file. According to one embodiment, a secured file or secured document includes two parts: a header, and an encrypted data portion. The header includes security information that points to or includes access rules, a protection key and a file key. The access rules facilitate restrictive access to the encrypted data portion and essentially determine who the secured document can be accessed. The file key is used to encrypt/decrypt the encrypted data portion and protected by the protection key. If the contents in the secured file are classified, the file key is jointly protected by the protection key as well as a security clearance key associated with a user attempting to access the secured file.

Usage of shared resources can be managed by enabling users to obtain different types of guarantees at different times for various types and/or levels of resource capacity. A user can select to have an amount or rate of capacity dedicated to that user. A user can also select reserved capacity for at least a portion of the requests, tasks, or program execution for that user, where the user has priority to that capacity but other users can utilize the excess capacity during other periods. Users can alternatively specify to use the excess capacity or other variable, non-guaranteed capacity. The capacity can be for any appropriate functional aspect of a resource, such as computational capacity, throughput, latency, bandwidth, and storage. Users can submit bids for various types and combinations of excess capacity, and winning bids can receive dedicated use of the excess capacity for at least a period of time.

A password management service located either on a user computer or in the cloud intercepts a user's attempt to create an account on a Web site. The user enters a sequence of a physical key combination and the service assigns a particular keyboard layout for this Web site. The service generates a password by combining the key combination with the assigned keyboard layout and returns this password to the user or to the Web site. The service stores the name of the Web site in association with the designated keyboard layout. Upon a subsequent login attempt, the service again intercepts the user's typing of the same physical key combination, generates the same password by combining the key combination with the previously assigned and stored keyboard layout, and returns the generated password to the Web site for authentication. A keyboard layout for a site may be chosen by the user, may be selected by the service, or a random layout may be generated. The service enforces a password constraint of a site by adding in the required characters, by requiring the user to choose a new key combination, or by using a different keyboard layout.

A touch curve memory 110 stores therein a touch curve formed by velocity values corresponding to touch data generated by a keyboard device 20. A correction coefficient generator 10 generates a correction coefficient composed of a ratio of one of the velocity values stored in the touch curve memory corresponding to one of the touch data generated by the keyboard device, in a maximum touch memory mode switched by a mode switch 21 (SW1), to a maximum value of the velocity values in the touch curve memory. A corrector 10 multiplies the correction coefficient generated by the correction coefficient generator by the respective velocity values stored in the touch curve memory, and then generates a touch curve formed by new velocity values. Accordingly, it is possible to provide a touch control apparatus and a touch control method which can obtain a touch curve, from which a touch response suitable for a user can be obtained, easily and in a short time.
