[0002] In the existing solutions, it often happens that when customers watch multiple different videos, they play the same video. After investigation, it is found that the common point of these videos is that the last N characters of the URI (Uniform Resource Identifier) are the same. It is guessed that the operator of the customer used a caching strategy for our video files, resulting in video hijacking

Embodiment Construction
[0023] The present invention will be described in detail below in conjunction with specific embodiments. The following examples will help those skilled in the art to further understand the present invention, but do not limit the present invention in any form. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of the present invention. These all belong to the protection scope of the present invention.
[0024] The video cloud platform video playback uri encryption and decryption method of the present invention comprises the following steps:
[0025] Step 1, conversion of base system, binary system is composed of 0, 1, octal system is composed of 0, 1, 2, 3, 4, 5, 6, 7, decimal system is composed of 0-9, hexadecimal system is composed of 0-9 and AF composition, these 0-1, 0-7, 0-9 numbers and letters are called the base of the system, then use 0-9, A-Z, a-z and some punctuation marks to organize i...

The invention provides a video playing uri encryption and decryption method for a video cloud platform. The video playing uri encryption and decryption method for the video cloud platform comprises the steps of: (1), performing conversion of a number system; (2), disrupting the system base number sequence; (3), performing video playing uri, and converting a physical storage path into a standard format; (4), performing a base encryption algorithm of yyyy-mm-dd in the uri, adopting a base62 algorithm and a base62 system base number representing method, and converting yyyy-mm-dd into yyyymmdd; and (5), performing uri base encryption algorithm of a flv video type file and the like. According to the video playing uri encryption and decryption method for the video cloud platform provided by theinvention, the video fluency can be kept; simultaneously, the uri encryption method is adaptive; the video type pcf itself is defined; the content is subjected to DRM encryption; encryption operationis carried out for the pcf video file type uri; therefore, the file is protected; and furthermore, the data security of the cloud platform is protected.
Description
technical field [0001] The invention relates to a video playback URI encryption and decryption method, in particular to a video cloud platform video playback URI encryption and decryption method. Background technique [0002] In the existing solutions, it often happens that when customers watch multiple different videos, they play the same video. After investigation, it is found that the common point of these videos is that the last N characters of uri (Uniform Resource Identifier) are the same. It is guessed that the customer's operator has used a caching strategy for our video files, resulting in video hijacking. At the same time, we conducted technical research on youtube (the largest video website in the world), Youku and other video websites, and found that they are using a technology called ShortUrl (a URL shortening technology), which makes videoId (video identification) become Short and rambling. And existing video playing uri form: 1, flv (FLASH video) video fil...
