Homemade PHP High anti-theft chain (not general high) (thinking)

Principle: Based on IP, resource ID, timestamp, disposable access_token,appkey (exposed to foreground) and appserect (background) to generate parameters, see below:

Browser Request page =/Background reference anti-theft chain code = Generate Access_token and bind access ip=> generate sign=> generate URL

For example: The original picture page is http://xxx.example.cn/pic.php?picid=1

Into http://xxx.example.cn/pic.php?picid=1&appkey=xxxxxxxxxxxxx&access_token=xxxxxxxxxxx&timestamp= Xxxxxxxxx&client=xxxxxxxxxx&sign=xxxxxxx

All with MD5 first do encryption, then with appid+ all data json+timestamp encryption, and then use salt encryption 16 times

The time will be ready to send the finished product!!
