The embodiment of the invention discloses a data processing method, a user side, a service platform, trusted hardware and a system. The method comprises the following steps: a user side generates a random number seed and sends the random number seed to a service platform; the service platform transmits the random number seed into trusted hardware; the trusted hardware signs the random number seed by using a private key derived from the trusted hardware to obtain a digital signature corresponding to the random number seed; the trusted hardware or service platform generates a random number based on the digital signature. By adopting the scheme, the whole-process control of the platform on the random number generation can be avoided, the fairness of the random number generation is ensured, the random number cannot be predicted by the user side and the service platform, and the unpredictability of the random number is ensured. 本发明实施例公开了一种数据处理方法、用户端、服务平台、可信硬件及系统。方法包括：用户端生成随机数种子，并将随机数种子发送给服务平台；服务平台将随机数种子传入可信硬件中；可信硬
