VeriSign IDN Patent Application

Application Number: 20110106924
Full patent application here by search for application number:

http://appft1.uspto.gov/netahtml/PTO/srchnum.html

Summary:

----------
Internet Domain Name Super Variants

Abstract

Systems and methods for registering a domain, including Internationalized Domain Names (IDNs), including receiving a request to register an IDN and determining a language category of the request. Code points of the request are converted to yield a generalized variant of the IDN. The generalized variant is compared to a stored database of registered IDNs that may include similar generalized variants of the registered IDNs. Based on the comparison, it is determined whether or not to resister the IDN. In the case the that ION registration is allowed the generalized variant of the IDN may be stored in the database to protect against later registration by similar IDNs. Converting the code points of the request may include identifying corresponding code points of variants within the language category, and converting each of the code points of the requested IDN based on a deterministic algorithm applied to the corresponding code points. The deterministic algorithm may be applied to a value of each of the corresponding code points to yield a representative code point from among the corresponding code points, and the generalized variant may include a representative code point for each of the code points of the request.

Haven't even had time to read it yet, let alone digest, but thought it was worth posting .....

Just a quick comment from the abstract: "In the case the that ION registration is allowed"

a) That's not English
b) What's an "ION" ???

Are patent applications really this shoddily written? Or perhaps the USPTO writes the abstract?

Re: VeriSign IDN Patent Application

This approach allows a single form of the Chinese IDN, but blocks all other forms from later registration. This solution has been recognized by the IDN Working Group of the IETF, which has defined an “IDL Package” as part of the JET Guidelines for IDN. However, because a single Chinese character can have many variants, domain names including several Chinese characters together can result in an overwhelming number of possible variants for a single domain name. Without a special approach the storage required to effectively block IDN names of significant length in Chinese language variants Can be prohibitive. Similar ways of dealing with this problem include other types of reserving or registering all potential variants of an IDN, which can present significant burdens as well. Known methods are also limited in their ability to interpret IDNs that may include different types of character variations within a name. For example, a user may attempt to register or resolve an IDN by inputting a mixture of traditional and simplified Chinese characters that a registration or resolution system may NI to adequately decipher when listed together.

SUMMARY

OF THE INVENTION
The present subject matter can provide benefits in improving the registration of domain names, including for example IDNs. Aspects of the disclosed invention provide ways of dealing with problems related to multiple character representation and variation in ways that known systems do not address, and without the onerous requirements of conventional solutions. Aspects of the disclosed invention may employ methods of simplifying the IDN using generalized representations, or “Super Variants”, of the IDN. The generalized representations may be stored in a database, such as a registry database, and used to deconflict registration of requested IDNs by comparing a generalized representation of the requested IDN with the stored generalized representations that represent previously registered or otherwise reserved, IDNs.

A domain name is made of code points, each with a known value assigned in Unicode. Common standards have been adopted for various languages and language variations, including, for example, traditional and simplified Chinese. According to aspects of the invention, for each code point or word-character in an IDN, all legitimate variants for a foreign language character or string of characters, such as Chinese language variants, will share the same generalized representation. Therefore, if a variant of a requested IDN is already registered, it may be recognized by the stored generalized representation in the system. By referencing the stored generalized representation, it may be determined whether a requested IDN is already covered by a registered IDN without the onerous requirements of blocking, reserving or registering all potential variants of an IDN. Aspects of the disclosed invention may also provide additional advantages, not recognized by conventional systems, of being able to accommodate mixed variations, such as Traditional and Simplified languages in a request to register the IDN or in a previously registered IDN. For example, the generalized variation may be sufficient to block all other variants, including mixed variant domains and requests.
