Abstract: A data storage method and a data storage apparatus are provided. The method includes determining a type of operating system of a host. A configuration file corresponding to the type of the operating system is stored in a data card connected to the host. A memory file system is established according to a first mounting information in the configuration file. A storage device is mounted according to a second mounting information in the configuration file. A correspondence between a storage space in the memory file system and the mounted storage device is set. The mounted storage device is used to store data that is to be stored in the data card.

Abstract: An embodiment of the present application provides technologies for detecting malicious content embedded in a content downloaded from an external source. The downloaded content converted into an opcode sequence by a web browser in a computing device. The opcode sequence is compared with a pre-stored opcode signature. The opcode signature comprises multiple sentences, and each sentence has multiple clauses. Each clause may include a matching opcode, a condition, an instruction, and an identifier. When a matching opcode in a clause matches with an opcode of the opcode sequence, and the condition as specified in the clause is determined to be true, the instruction in the clause is taken and next sentence identified by the identifier is taken to match the opcode sequence. Eventually, the last taken clause in the opcode signature may instruct whether opcode sequence contains malicious code.
