Abstract: Before the audit of internal units, the audit department needs to collect and sort out all kinds of materials as the audit basis, including Internet public data and confidential data within the unit. When collecting confidential data inside the object, it is usually necessary to transmit data through encrypted media or auditors to work directly on the site. This paper proposes an acquisition architecture based on domestic TCM chip encryption and edge cloud collaboration. It can simultaneously collect the Internet public data and the confidential data inside the object, and encrypt data through the TCM chip solidified in the hardware to ensure that only the designated machine can read the confidential materials. The audit data edge cloud collaborative collection architecture based on domestic TCM chip encryption can realize the cross network transmission of classified data. According to the  feedback of actual useres, taking the transmission of classified data using encrypted media as the comparison scenario, after adopting the collaborative collection architecture, it can quickly enter the audit work locally, and the data acquisition efficiency can be improved by 30% on average. The working time of non local audit is reduced by 3 days~4 days to effectively improve the audit efficiency.
