Recently, the organization launched the pan financial video witness system solution, which fully supports real-time audio and video recording through the risk disclosure of the financial transaction process, realizes business tracking, and provides "double recording" technical services in line with policy supervision for Pan financial platforms such as banks, securities and insurance.In addition to the "double recording" function, the video witness system can be expanded and applied to multiple business processing scenarios such as investment counselor, face-to-face signature, insurance loss determination, etc. in the past, businesses that needed to carry a large amount of data to and from financial outlets for many times can be handled remotely through the video witness system, saving time and effort, helping the pan financial platform improve service efficiency and reduce operating costs.Expert financial investment adviser: communicate and consult with investment advisers in the financial system remotely and face to face through video calls. Witness face-to-face signature: users can complete online signature only by video dialogue with customer service personnel in banking, securities, insurance and other industries through mobile phones, computers and other portable devices. Self service handling and one-way face-to-face signing: financial institutions allow users to remotely handle simple businesses such as card opening and account opening under the guidance of PPT and voice through the form of PPT demonstration and voice broadcast.Financial double recording and risk disclosure: in the process of financial transactions, through the combination of video witness, PPT demonstration and voice broadcasting, comprehensive and real-time audio and video recording can be kept at the end of the risk disclosure link to record the whole process of business handling. Remote accident and insurance loss determination: after the accident, the owner directly connects the loss assessment personnel by video through terminals such as wechat applet, and the insurance agent remotely guides to complete the survey and loss determination, so as to quickly promote the compensation process.That is, the pan financial video witness system has powerful functions. In addition to meeting the general needs of the financial industry, based on the self-developed voice and video terminal engine, the system can also flexibly and quickly meet the customized needs of customers:That is, it supports the setting of multiple resolutions, code rate and frame rate, and supports screenshots of real-time video. The system provides network adaptation, intelligent rate adjustment, jitter buffer and other functions to achieve 100ms ultra-low delay, stable and smooth audio and video calls, audio and picture synchronization, no Caton, no flower screen and black screen. The reliability of video witness process can reach 99.9%, which can ensure high fluency and availability even in weak network environment.Through the preset system voice, unify the voice broadcasting standard, improve the mode that the teller reads the risk disclosure content in the traditional video witness system, reduce the uneven effect of risk disclosure, and improve the customer service standard. At the same time, standard voice broadcasting is also conducive to improving the audit efficiency of background business personnel. Through the PPT synchronization demonstration, customers can see the PPT screen synchronously when listening to the voice broadcast, which is easier to understand. In the process of video witness, the system also supports PPT presentation screen recording.That is, the recording storage provides a local recording mode, which performs audio and video synthesis and file writing on the client, the client and PPT pictures through the PC at the seat end, and then uses the two modes of "recording while uploading" and "post uploading" to transmit to the background storage, so as to ensure the integrity and stability of video recording and reduce the picture jam caused by real-time transmission network jitter.That is, the video witness system supports customized settings for the screen synthesis display mode, provides the synthesis display including double screen, three screen and multi screen, and provides the synthesis recording and display including seat end and client, PPT synchronous demonstration, voice playback and time watermark. The intelligent queuing function can provide a queuing mechanism for multiple people to process business at the same time, follow the queuing logic of conventional offline business, conduct business processing in the order of number first come first served, and provide functions such as queue location reservation, reservation queue jumping, disconnection and reconnection.Based on the excellent audio and video real-time communication capability, that is, the video witness system has been optimized and upgraded in terms of service according to the characteristics of the pan financial industry, which is more in line with the security needs of the financial industry and users' habits. Involving massive financial data management, the financial industry puts forward higher requirements for data security. That is, the structured financial dual recording solution supports the privatization deployment scheme and the fully redundant cluster deployment scheme, so as to improve the security of the scheme from the different dimensions of login and permission security:Support HTTPS mode to ensure the security of transmitted data; Support integration and docking with the existing identity authentication system to ensure user login security; Support the dual factor verification mechanism at the Internet side entrance. The login verification must meet the dual factor conditions at the same time to allow access. None of them is indispensable to ensure the security of system login and access. Permission securitySupport the role permission management mechanism, which can be integrated and connected with the existing permission system; Users can query different business data according to role permissions; Intelligent queuing, video witness, video recording and other functional modules are designed independently and flexibly. Different functional modules can be used separately according to actual application scenarios. For example, some business processing logic can be added between queuing and witness, or other third-party queuing services can be used to connect to the instant video witness function.That is, it provides SDK designed for financial video witness scene packaging: 1) User Mobile SDK: it supports IOS and Android systems, integrates video witness capability and Queuing service capability, and makes more flexible packaging for video acquisition, preprocessing, codec and video rendering, making the SDK easier to integrate. 2) Electronic SDK on the agent desktop: it supports the window system and integrates the capabilities of video witness, video recording and queuing services. For the agent business scenario packaging design, it is more suitable for the agent business and realizes faster.
