Unlike the technology for a program downloaded through conventional broadcast waves, in the case of downloading a program via a network, there is a possibility that such program will be activated without noticing that the program is tampered with. For this reason, when a program is downloaded via a network, a file hierarchy for the program located on a server is constructed in a local area of a terminal. Subsequently, the authentication of the program is performed with respect to the file hierarchy constructed in the local area, and the credibility of the program is guaranteed.

According to a conventional technique, in the case where a program is stored into a non-volatile memory once and then activated, authentication of the program is performed immediately before such activation. However, calculations such as decryption of encrypted values are required before the activation of the program starts, which causes the problem that responsiveness is decreased in proportion to the time required for calculations. In order to solve this problem, authentication of a program is performed immediately before such program is stored, so that no authentication is performed or only a part of the authentication is performed to verify the validity of certificates at program activation time.

Conventionally, when the version of a program has been upgraded, the whole of a currently stored program needs to be deleted to be replaced by a new program, and authentication needs to be performed again on such new program when it is activated. However, since the whole of the program is required to be stored and authenticated even when only a part of such program has changed, it consumes time and leads to the decrease in responsiveness. In order to solve this problem, the present invention extracts a difference between a new program and a currently stored old program, when such new program is to be stored, and the new program is to be stored after authentication is performed only on such difference.

The invention relates to a mixed-type trust system and a method in a vehicle-mounted ad-hoc network. The mixed-type trust system and the method in the vehicle-mounted ad-hoc network comprise vehicle-mounted components and basic facility components. Each vehicle-mounted component is installed and operated on a vehicle and comprises an interface module, a decision module, an entity reputation calculation module, an event reputation calculation module, an event spreading module, a communication module, an event processing module and a sensing module. Each basic facility component is installed and operated on a roadside unit (RSU), the RSUs are connected through a broadband wired network or a wireless network, and each basic facility component comprises a reputation storage module and a reputation synchronization module. The mixed-type trust system and the method in the vehicle-mounted ad-hoc network enable the vehicles to rapidly and accurately inquire and update reputation, the correctness of alarming information is judged, and therefore the vehicle receiving fake information can not be misdirected.

The invention relates to a terminal peripheral starting method and device. The method comprises the following steps: acquiring equipment information and terminal information of a terminal peripheral; authenticating the terminal peripheral according to the equipment information and the terminal information of the terminal peripheral; and starting the terminal peripheral after the terminal peripheral passes authentication. Through the technical scheme, the peripheral of the terminal can be prevented from being replaced maliciously; the reputation of a producer is ensured; and the quality of products is ensured for a user.

The invention discloses a color character coding method and a decoding method thereof, which solves the problems of low security and affecting product appearance in anti-counterfeiting code technology. The encoding method of the colored characters includes: (1) selecting N different colors; (2) formulating an N-ary encoding library and matching its base with the selected color; (3) inputting source information and converting it into M-ary Encoding; (4) Convert the M-ary code to N-ary code to obtain the corresponding data; (5) Use the color that matches the base of the N-ary code library to replace the data and arrange and combine to form a color character; (6 ) to output colored characters. The decoding method of the colored characters includes: (1) using terminal equipment to identify colored characters and replacing them with M-ary codes; (2) converting M-ary codes to UNICODE or ASCII codes; (3) terminal equipment converting UNICODE or ASCII code is converted to source information and output. The anti-counterfeiting code of the present invention is novel and has high security.

Provided are a method of providing a call taxi service and a call taxi service server providing the method, in which a call taxi service is provided by using human and physical network resources of a plurality of call taxi companies. Accordingly, human and physical networks for the call taxi service become abundant, and thus a dispatch success rate regarding a call taxi request is increased and a dispatch time is reduced.

The invention relates to an anti-counterfeiting mark, in particular to a manufacturing method of a shape memory anti-counterfeiting mark with permanent memory information. The manufacturing method of the shape memory anti-counterfeiting mark with the permanent memory information comprises preparation of a high-molecular polymer material. The high-molecular polymer material is prepared by the following components, by weight, 100 parts of polylactic acid, 0.1-1 part of polycaprolactone, 0.1-1 part of deoxyribonucleic acid (DNA) printing ink, 0.01-0.2 part of antioxygen and 0.1-0.3 part of inorganic filler. The manufacturing method of the shape memory anti-counterfeiting mark is simple and easy to operate and easy to achieve. The anti-counterfeiting mark can distinguish the true from the false in duplex mode, can protect consumer benefit, guarantees manufacturer benefit and product reputation, and is particularly suitable for being applied to high-end products. In addition, polylactic acid and polycaprolactone are both biodegradable. The anti-counterfeiting mark is an environment-friendly anti-counterfeiting mark.

The invention relates to a connecting structure and a connecting method for a tapered interface and a plastic connector of an air inlet pipe of an air filter. The connecting structure comprises a tubular plastic connector and the air inlet pipe of the air filter, wherein the plastic connector is fixedly connected into the tapered interface formed in a pipe wall of the air inlet pipe of the air filter and is communicated with the air inlet pipe of the air filter; inner peripheral walls of the tapered interface close to an upper port and a lower port are respectively provided with a circle of inward concave grooves; two circles of outward convex bulges are respectively formed on the periphery of the plastic connector; the plastic connector is located in the tapered interface; and the two circles of outward convex bulges are respectively embedded in the grooves at the upper port and the lower port of the tapered interface. The connecting method comprises the following steps: forming the plastic connector; placing a mould into a glue injector and heating; coating adhesives on the plastic connector; placing the plastic connector into the mould; injecting glue into the mould, vulcanizing and shaping; and taking out a shaped product. The connecting structure provided by the invention has the advantages that the process is simple and convenient to operate, the appearance is good, the working hours are saved, the yield is increased, the materials are saved, the cost is lowered and the quality of the product is increased.
