The invention discloses a radio frequency identification (RFID) safety communication method established according to an ultra-lightweight RFID bidirectional authentication protocol. By adoption of the method, the security problems of a low-grade tag RFID system can be effectively solved. The method has the main characteristics of security, high efficiency, simplicity and practicability. A tag is only required to provide simple operation such as random number generator operation, exclusive-OR operation, modular operation (MOD) and displacement. Resources required by the simple operation are extremely limited, so the scheme is in complete accordance with an EPCglobal C1G2 tag specification, has the characteristics of low storage cost, low operation cost, low communication cost, novel and simple algorithm and the like, and is easy to implement. The method has the advantages that the problems about synchronization of the tag and a rear-end database key, forward security and security privacy (privacy leak, flow analysis and positioning tracking) can be effectively solved, and the common security problems of an RFID system about imitation attack, cloning attack, monitoring attack, replay attack and denial-of-service attack are solved. The method is quite applicable to solving the security problems of an EPCglobal C1G2 RFID tag.

An ID tag for RF transmitting its own tag ID information is disclosed. The ID tag comprises an ID storage for outputting the tag ID information stored therein; an ID concealing unit that conceals the tag ID information based on a certain value relating to time and outputs a concealed ID; a time information concealing unit that conceals the certain value based on a stored tag unique value and outputs concealed information; and a data outputting unit that receives and combines the concealed ID and the concealed information, and outputs combined data.

An automatic bidet has a toilet seat fixedly mounted to a toilet, a bottom sprayer disposed in the toilet seat that can stretch out freely from the toilet seat, and a handheld sprayer that is separated from the toilet seat. A water storage tank, a booster pump, a liquid valve are disposed in the toilet seat and are connected in sequence. The water in the water storage tank flows respectively to the bottom sprayer and the handheld sprayer from the liquid valve under the pressure of the booster pump. The handheld sprayer comprises a hollow handle portion and a curved head portion having a bulge. The top of the bulge is provided with a mammilliform water outlet. The automatic bidet is capable of cleaning anus and private parts of a male or a female, and the handheld spray device can be used to carry out enema by a user and the wastes can be let off completely. The whole process can be done under the condition that a user sits on the toilet. The wastes directly enter the toilet and the user's clothes are kept clean. The user can independently operate the present invention without help from other people so as to avoid the embarrassment of exposure of privacy.

A data management apparatus includes an index generation unit configured to subdivide an entire interval of data into bucket intervals, allocate indices for the respective bucket intervals, transform the bucket intervals having the allocated indices into bucket intervals of specific lengths, and generate bucket-based indices for pieces of data included in the bucket intervals of the specific lengths. The data management apparatus further includes a data management unit configured to transmit the encrypted data and the bucket-based indices to a server-side data management apparatus in order to store the encrypted data, transmit a user query to the server-side data management apparatus in order to search for a desired encrypted data, and decrypt encrypted data corresponding to the user query from the server-side data management apparatus. The user query includes the index of first bucket interval and the index of second bucket interval neighboring to the first bucket interval.

A control method including: receiving first transaction data including a first electronic signature from the a home of a first user; verifying whether the received first electronic signature included in the first transaction data is valid; verifying validity of the received first transaction data; when the first electronic signature and the validity of the first transaction data are verified successfully, executing a first consensus algorithm for the first transaction data; and when the validity of the first transaction data is verified according to the first consensus algorithm, recording a block including the first transaction data in a distributed ledger. The first electronic signature is a group signature assigned to a group to which the first user belongs.

The invention discloses a human body sitting posture detection method based on a depth camera, and relates to the field of image processing. The method comprises the following steps that a depth imageand a color image of a back area of a human body are acquired, a foreground area of an image is acquired by combining the depth image and the color image, and whether the sitting posture of the humanbody is correct or not is calculated by the partial area of the foreground area, so that the purpose of the invention is achieved. According to the non-contact type sitting posture monitoring methodbased on the machine vision, human back data is collected by means of the depth camera, images can be obtained in real time through a sitting posture monitoring algorithm, sitting posture monitoring is completed in a full-automatic mode, and when the sitting posture is abnormal, computer-side human-computer interaction software reminds a user to correct the sitting posture in time. A sitting posture of the person is closely related to the spine state, so that the collected back data is most accurate to analyze the sitting posture, and meanwhile, the privacy problem caused by the collection ofhuman face information can be avoided.

The invention relates to a privacy protection method and device for Wifi fingerprint positioning. The privacy protection method for Wifi fingerprint positioning comprises the following steps that a server extracts all the Wifi fingerprints and fingerprint metadata; a client terminal collects Wifi signal intensity values in the peripheral environment and generates a public key and a private key according to the asymmetrical encryption algorithm, encryption is respectively conducted on the collected Wifi signal intensity values by the public key and a positioning request is sent to the server; the server calculates the fingerprint distance between all the Wifi fingerprints and each encrypted Wifi signal intensity value and transmits multiple sets of encrypted fingerprint distance data to the client terminal; the client terminal uses the private key to decrypt the multiple sets of the encrypted fingerprint distance data, and determines the current location of the client terminal according to the Wifi fingerprint corresponding to each decrypted fingerprint distance datum and the received fingerprint metadata. The privacy protection method and device for Wifi fingerprint positioning solves the privacy problem in an existing WiFi fingerprint positioning technology, and can protect the location privacy of a user and the data privacy of a service provider.

The invention belongs to the field of education, and provides an online live broadcast method and device based on image cartoonization, and electronic equipment, the method is used for identifying anoriginal image in a live broadcast video stream in real time and cartoonizing a face image in the original image, and the method further comprises the steps of collecting a real face data set and a cartoon face data set, establishing a training data set; based on the generative adversarial network, establishing an initial figure cartoon head portrait generation model, and performing alternate training by using the training data set; determining a loss function according to a constraint rule, and controlling the alternate training by using the loss function to obtain a final figure cartoon headportrait generation model; and obtaining a to-be-converted original image in the current live video stream, and converting a face image in the original image into a cartoon face image by using the final cartoon head portrait generation model. According to the invention, the consistency of images before and after the figure cartoon image is generated in multiple dimensions such as color, position,edge, texture, head portrait attribute and the like can be ensured.
