Description
Technical Field
The invention belongs to the technical field of network information, and particularly relates to a browser video uploading frame intercepting system and a method thereof.
Background
With the popularization of 5G technology and the iteration of coding technology represented by LDPC codes, video applications are loaded through a mobile terminal, and then uploading and downloading operations are performed on videos or pictures, which is becoming one of the more popular user-side entertainment means.
Generally, on a mobile terminal or a PC side, a user mainly obtains and downloads videos through a mobile application or a browser. The video file or the video source code is pulled from the remote video server to the local browser, and is played through the built-in video decoding and playing function of the browser or through plug-in and other forms. And if the user needs and has the authority, editing, intercepting, downloading or uploading the video and the like can be further executed.
The browser is used as a universal webpage and an image information browsing window, and provides a visual graphical browsing interface for a user. Them banus invented the first web browser in 1990. For mobile terminals and PC terminals, the following browsers are currently mainstream: CHROM. Chrome is a truly user-friendly web browser, and also provides themes and plug-ins for users. Nevertheless, these many extensions are designed to make it easier for the user's search engine to optimize the relevant work, and these extensions are designed to use Web technology as Java, CSS and HTML. Google adds an admirable security feature for every user. FIREFOX. Contains many advanced functions including incremental lookup, private browsing, spell checking, smart bookmarking, tag browsing, etc. It implements many Web standards such as the subsets HTML and XML under the standard universal markup language, XHTML, SVG 1.1 (partial), CSS (extended support in addition to the standard), ECMAScript (JavaScript), DOM, mathML, DTD, XSLT, XPath, and PNG image files (including transparency support). The browser Firefox is truly user-friendly and easy to install, even though they may help those users who want to use it in search engine optimization. SAFAR. Designed by Cupertino, apple, a U.S. multinational technology corporation. For the first time Safari introduced Mac OS X pantoher in 2003, and its remarkable performance gained global goodness. The apple company's own kernel is also the kernel used by apple's Safari browser. The method uses a Webkit engine, comprises a Webcore typesetting engine and a JavaScript core analysis engine, which are derived from KHTML and KJS engines of KDE, are free software, authorize under GPL treaty, and simultaneously support the development of a BSD system. Webkit opens source code at the same time, and is not limited by IE and Firefox in the aspect of safety, so the Safari browser is very safe. Safari believes to be the best networking software for Mac system users because it can achieve an admirable result or a better internet experience. IE (Internet Explorer). Internet Explorer is a web browser from microsoft corporation. The Internet Explorer technology is closed and supports only a few CSS, HTML, and DOM features (and many implementations are problematic). Not only do the competitors Firefox and Opera lead Internet Explorer in this respect, they also have native XHTML support. As such, internet Explorer has always failed the Acid2 test to verify the degree of CSS standard support. Another significant drawback of Internet Explorer arises from the PNG format, and this problem is only solved in Internet Explorer 7. However, internet Explorer 7 will suffer a significant degradation in performance when accessing web pages containing transparent PNGs. Internet Explorer is suitable for all systems using the Windows operating system. Opera. One of the "Opera" by Opera software corporation is the fifth of the ten best web browsers in the world in recent years. Its functions include internet external member, powerful encryption, security, internet external member etc. The European and Peng browser supports intelligent pre-reading, intelligent zooming and gesture operation, is additionally provided with a fashionable and personalized interface design, and supports the whole-network browsing of WAP (wireless application protocol) and WWW (world Wide Web) sites of the mobile phone. Meanwhile, the mobile internet browsing reminding device has a built-in browsing reminding function and provides mobile internet experience for users.
A user can often select to store or upload an interested video after obtaining the video at a browser end, and in the browser video uploading in the prior art, the user generally directly downloads the browser video and then uploads the downloaded video by storing a cover page, and compatibility difference caused by the non-standardization problem of the browser is not considered, and the downloaded video data is leaked or tampered due to security attacks in various forms possibly caused by different browsers. Meanwhile, due to the adoption of a third-party browser, user data at a system end cannot be strictly kept secret, and user information is leaked to a certain degree. An attacker can attack the widely used browser by only acquiring the version of the non-standardized browser and adopting plug-in or malicious code injection and other modes, so that the probability that the browser is attacked by various types of attacks is greatly increased. Furthermore, in the process of uploading the video frames, since the video frames are not intercepted or only simply intercepted, the intercepted information is not reasonably utilized, and the verification of uploading the video frames of the browser cannot be realized based on the intercepted information in combination with other comparison information.
The invention provides a method and a system for intercepting uploaded frames of a browser video. By using the standardized second browser instead of directly executing video interception and video uploading in the first browser, network security risk isolation is realized, and video tampering caused by direct injection attack on a plug-in or malicious code of the first browser is avoided. Meanwhile, based on video frame interception, the invention combines three information of data pair parameter transmission, semi-public information transmission and video uploading frame interception information transmission, thereby avoiding the hidden danger of network security attack and data tampering caused by single channel video frame interception and uploading, and ensuring higher system security and user data leakage prevention performance in the process of uploading the browser video frame.
