A system an method for distribution of electronic data over a network infrastructure that includes a client device for operation by a user desiring to receive the electronic data and server that contains the electronic data and offering the electronic data for downloading to the client device via the network infrastructure. The client device communicates a compound data key that includes a unique serial number associated with a particular piece of media to which the electronic data is to be stored to the server, vendor information and user information. The server encrypts the electronic data using the compound key, and downloads the encrypted electronic data to the client computer, where the client computer writes the encrypted electronic data to the particular piece of media such that the encrypted electronic data may only be accessed from the particular piece of media. The electronic data is decrypted for use by the apparatus or another device attached to the apparatus using the compound key as a data key, and the data is accessible from only the one piece of media having the unique serial number and is not accessible from any other media having a different or no identifier. In an alternate embodiment, the apparatus for reading the encrypted electronic data is connected to a general purpose computer having a media drive which reads the unique serial number and the electronic data from the one piece of media. The apparatus comprises an application specific integrated circuit which controls and executes instructions to accept the electronic data and the unique serial number from the general purpose computer.

In order to facilitate the requesting of desired information from a graph database that stores a graph, a system may translate an initial query into a query that can be executed against the graph database. In particular, using primitives, the system may translate a query associated with a type of database (such as a relational database) into the query. The graph may include nodes, edges between the nodes, and predicates to represent and store data with index-free adjacency. Moreover, the primitives may include: a rule based on edges in the graph that expresses a relational schema in the type of database, and information associated with a compound key that specifies a relationship between nodes, edges and predicates in the graph corresponding to a table in the type of database. Then, the system may execute the query against the graph database, and may receive a result that includes a subset of the graph.

The invention provides a method, a chip and a device for implementing the functions of compound keys of the key module of an embedded system. The method comprises the following steps: the embedded system executes keystroke interruption and records the keystroke after detecting the keystroke is pressed; the embedded system starts a timer and then rescans if other keystrokes are pressed in accordance with scheduled time intervals, if so, records the new keystrokes; the embedded system scans if all the keystrokes are released, and then disables the timer if all the keystrokes are released; then the embedded system produces the key assignments of the compound keys according to the keystroke records and submits the program prior to the keystroke interruption. The timer is additionally arranged in the system on the basis of the existing array keystroke module. The system starts the timer and then rescans and records other keystrokes in accordance with the scheduled time intervals after detecting a keystroke interruption. Therefore, under the condition of one system interrupted, the invention can realize the functions of the compound keys by obtaining the responding of a plurality of keystrokes. Besides, the proposal of the invention has no restriction to the keystroke sequence and quantity, and supports the composite of any keystroke and a plurality of keystrokes.
