Abstract: An analysis method of a financial securities product value model based on artificial intelligence includes performing a determining step, a data acquiring step, an analyzing step and a strategy generating step. The determining step is performed to determine that the customer is one of a long-term investing customer and a short-term investing customer. The data acquiring step is performed to acquire one of a plurality of long-term trading parameters and a short-term trading data. The analyzing step includes dividing the financial securities products into a plurality of groups, and calculate a plurality of classify conditions and analyzing a product relevance and a purchasing sequence of the financial securities products. The strategy generating step is performed to generate a purchasing strategy according to the groups, the classify conditions, the importance value of each of the long-term trading parameters, the product relevance and the purchasing sequence.

Abstract: An anonymity authentication method for wireless sensor networks is provided. A smart card carried by a user is used to provide two-factor verification protection. Moreover, a random factor and a hash function operation are introduced for participating an operation of the transmitted messages in all phases. Moreover, the operation of the transmitted messages uses only hash function and XOR operator.

Abstract: An anonymity authentication method in multi-server environments is provided. When a user switches between various remote servers, it is not necessary to perform many times of complicated verification procedures, only a set of user identity and password is required for switching between the different remote servers. Moreover, the operation of the transmitted messages uses only hash function and XOR operator, and a random number is also applied thereto. Therefore, the anonymity authentication method of the present disclosure has high computational efficiency and high security.

Abstract: An anonymity authentication method for global mobility networks is provided. When a mobile user (MN) roams from an inner network to an outer network, a random number is introduced for participating an operation of the transmitted messages either in a registration procedure between the mobile user and a home agent (HA) or in a mutual verification procedure between the mobile user, the home agent, and a foreign agent (FA). Moreover, the operation of the transmitted messages uses only hash function and XOR operator. Therefore, the anonymity authentication method of the present disclosure has high efficiency, high security and low cost.

Abstract: A parking lot management system comprising a computer host, a handheld device, an entrance sensor, an entrance camera, an entrance stop, an exit sensor, an exit camera, and an exit stop is disclosed. The handheld device interactively transmits data with the entrance sensor and the exit sensor by near-field communication techniques. Each of the entrance camera and the exit camera takes a photo and acquires a license plate number of a vehicle and communicates this information with the computer host. After the computer host confirms and verifies some specific data, the computer host sends instructions to the entrance stop or the exit stop for allowing the vehicle to either enter or exit a parking lot. When exiting the parking lot, the parking fee is paid by the electronic wallet of the handheld device.

Abstract: A pruning hook includes a handle unit, an adjusting unit mounted on the handle unit and a cutting unit mounted on the adjusting unit. The adjusting unit includes a support member mounted on the handle unit, a fastening member releasably mounted on the support member and an adjusting member having a first end provided with an adjusting ball rotatably mounted between the support member and the fastening member and a second end provided with a locking tube connected with the cutting unit. Thus, the adjusting ball of the adjusting member is rotatable and movable between the support member and the fastening member so as to adjust the angle and position of the cutting unit relative to the handle unit in a spherical and three-dimensional manner.

Abstract: A pair of gardening shears include a first pivot base having a first blade and a first handle, a second pivot base pivotally connected with the first pivot base and having a second blade and a connecting portion, a mounting base having a second handle connected with the connecting portion to drive the second pivot base relative to the first pivot base, and a plug having an insert which extends through the mounting base, the first pivot base and the second pivot base and has an inner portion provided with a finger hole. Thus, when a user is operating the first handle and the second handle, the finger hole of the plug allows passage of the user's finger, so that the user can hold the first handle and the second handle stably to operate the shears smoothly.
