Method and system for determining a probability of entry of a counterfeit domain in a browser

Embodiments of the present invention provide a method and system for determining a probability that a suspected domain name of a domain accessed using a universal resource locator (URL), which can be entered as a character string into a browser associated with a client in a net environment, is a counterfeit of a legitimate domain name. Characters in the suspected domain name can be identified as known as likely to be deceptively substituted for corresponding legitimate characters of a legitimate domain name. An alternate domain name is generated by substituting predetermined characters with the corresponding legitimate characters. An attempt can be made to resolve alternate domains of the alternate domain names. If the names are successfully resolved, a non-zero probability is assigned to the suspected domain name as being counterfeit.

The invention relates to a method for obtaining high-purity sulphur from Claus reactive tail-gases, which belongs to the technical field of environmental protection. The method comprises steps as follows: (1) Claus tail-gas is preheated to reach the temperature between 160 DEG C to 300 DEG C; (2) the preheated gas enters a reduction reaction furnace filled with selective reaction catalysts to perform reduction reaction; (3) liquid sulphur is separated out of the reacted process gas via a condenser; (4) the process gas performs direct oxidization reaction inside a direct oxidizing reactor after being compensated with oxygen and preheated again; (5) liquid sulphur is separated out of gas on an outlet of the reactor via a sulphur condenser and a separator, tail gases after burned are cooled, washed by using an alkaline liquor and then discharged. The method overcomes the shortcoming that sulphur can not be produced by a traditional tail-gas hydrogenation reactor, improves total recovery efficiency of sulphur in a single process, and has the advantages of saving energy, lowering H2 consumption amount, reducing volume of absorption towers, decreasing arranged devices, lowering manufacturing cost and reducing operating load of the overall set of devices.
