Abstract: In a method for protecting software of a computing device, a hypertext preprocessor (PHP) software program of the computing device is encrypted using an encryption rule to obtain an encrypted file. When the encrypted file needs to be decrypted, the method determines whether a predetermined hardware lock is connected to the computing device. When the predetermined hardware lock is not connected to the computing device, the method displays a prompt that indicates the predetermined hardware lock is not connected to the computing device. When the predetermined hardware lock is connected to the computing device, the method decrypts the encrypted file with a decryption rule corresponding to the encryption rule.

Abstract: In a method to connect a server to a network device, the method generates a communication process to connect the server to a network device. The method separates an independent sub process form the communication process to connect the server to the network device, which is accompanied by an automatic end of the communication process. The method further creates a communication connection between the server and the network device.

Abstract: An electronic device for managing an electronic map provides a service for accessing the electronic map of a first security system. The electronic device further includes an abstract electronic map layer embedded in the first security system and a second security system. The abstract electronic map layer embeds an uniform resource locator and a loading scheme of the electronic map in a first application programming interface (API) of the first security system and a second API of the second security system.

Abstract: A method for controlling access to an electronic device, the electronic device determines one or more selected colored shapes in response to receiving selection signals generated by a user selecting the one or more colored shapes, sequentially numbers the selected colored shapes to obtain numbering information. When the numbering information matches prestored unlocking numbering information, the electronic device is unlocked.
