Abstract: An online payment system comprises a payment server and a payment client. The payment server is configured to generate a unique identifier of a commodity/order and a random number as a challenge code, and to generate a two-dimensional code based on the unique identifier of the commodity/order and the challenge code, and is further configured to display the two-dimensional code on a display device. The payment client is configured to read the unique identifier of the commodity/order and the challenge code in the two-dimensional code from the display device, and is further configured to send a payment account, the unique identifier of the commodity/order, and a reply code to the payment server, and to perform a payment operation on the basis of the payment account, the unique identifier of the commodity/order, and the reply code.

Abstract: A method for sample alignment is applied to a first participant system, where a first trusted execution environment is deployed at the first participant system. The method includes, in the first trusted execution environment, obtaining at least one first sample identifier of the first participant system; through the first trusted execution environment, obtaining at least one second sample identifier of the second participant system from the second trusted execution environment, where the second trusted execution environment is deployed at the second participant system; in the first trusted execution environment, determining the first initial intersection of the at least one first sample identifier and the at least one second sample identifier and performing the shuffle processing on all first target sample identifiers in the first initial intersection to obtain the first target intersection; and based on the first target intersection, determining the first sample alignment result.

Abstract: In embodiments, a server receives an HTTP protocol-based access request sent by the client; when the server determines that the access request comprises a preset identifier and the current identifier value corresponding to the preset identifier matches any of historical identifier values in a historical identifier set stored in the server, the server determines a user seed from the historical identifier set according to the current identifier value, the historical identifier set comprising a corresponding relationship between historical identifier values and user seeds, the any of historical identifier values being generated by the server on the basis of a user seed and a random number corresponding to the historical identifier value, and the user seed being used for identifying a same user recognized by the server on the basis of the access request; the server tracks an access behavior of the user seed.
