CN1484905A - Substituting URL attachment in forwarding electronic content - Google Patents

Abstract

A service on the data network validates whether an accessory of the E-mail of the sender has origin electronic document copy obtained from the data network. If the document can be derived from the origin, the service removes the accessory from the E-mail and applies a URL to replace accessory in order to save bandwidth and memory space.

Description

In the forwarding electronic content process, substitute annex with URL

The present invention relates on data network,, send or distributing electronic content for example on the internet.The present invention be more particularly directed to E-mail communication.

Have tendency to show, in the content submission process on the internet, so-called virus-type issue will play an important role." virus-type issue " means a kind of like this mechanism: wherein, a content propagation and a colony that is spread in the end user, its mode extremely is similar to the propagation and the diffusion of virus.This notion is not exist explicit publication channel.From user to user, transmit content, for example, by the content that the young man issued of send Email.Napster is another example, and wherein, a server provides a contents table, to such an extent as to the user can select copy from other user's PC.A kind of form of described mechanism is that the user finds one section content in a certain place on Web, sends it to a certain friend by Email then.Attaching to the music file of Email, or particularly under the situation of video file, the size of message, and thereby the use that causes to bandwidth may be sizable.Usually, this annex comprises the file of a certain pop artist or slavish copying film.

The form that inventor's suggestion is issued with virus-type reduces the use to bandwidth.For this reason, for example, before the annex of Email is sent to the addressee, uses mail server or, consult the annex of Email by the special e-mail program on the PC of transmit leg.The purpose of consulting is: determine annex whether be people be very familiar to can be in one section content in many sources, for example, can be in one section content of a very close targeted customer's (addressee) a server.In this case, then substitutes annex by a much smaller pointer.Before this pointer was submitted to the targeted customer, targeted customer's server was recognized this pointer, and a local copies of attached respective media files.In addition, also can automatically substitute annex by pointer fully, and the recipient will use this pointer searching file.A further embodiment of the present invention verifies on sender server or recipient's server whether source user is authorized to issue respective media files.If unauthorized, then can substitute this document or the Email source user that rebounds by a message that mails to the targeted customer, and with an alert message, or source user can select payment selection is provided for issue, or the selection of defrayment can be provided to the targeted customer.

One aspect of the present invention relates to the method for communicating of the content information of a kind of control from user to the transmit leg.As the above mentioned, wherein whether be authorized to exchange content information, and/or whether be authorized to received content information, carry out this interchange conditionally according to the recipient according to transmit leg.When must labelling, with can be the time, can use identification procedure checking transmit leg and/or recipient whether to be authorized to send and/or receive this content from the availability of another source search for content to content information.For example, in view of copyright protection or content classification, can apply restriction to content release.Why carry out classification, be because some content to be regarded as for the minor be unaccommodated.If the recipient has an email account, then he can have profile, for example creates in when registration, and this profile is pointed out that the content of some type can not be transmitted and given this people.

Another aspect of the present invention relates to instant message and handles (IM).It is the communication service that a user that the IM program has been installed opens the private chat chamber of a certain permission establishment and another person's chat.The chatroom is a channel of having created the communication data path of an equity, is used for text message and handles or (PC) video conference.Usually, when the another person in the tabulation of every this user's private chat was online, instant message processing system was just warned this user.This user can start the chat conversations with this people.Stream file in IM (the being real-time) occasion is that people are very undesirable, because the big communication bandwidth of stream file demand.Comparing with stream file, is to transmit or transmitted pointer to file more easily, and the recipient can use this pointer to download or fluidisation this document from another source.

Below will be by way of example, and, explain the present invention in more detail with reference to accompanying drawing.In these accompanying drawings:

Fig. 1 is the flow chart of the operation in the method for the present invention; And

Fig. 2 is the structure chart of a system of the present invention.

Fig. 1 is the flow chart of the operation in the method for the present invention.In step 102, the user prepares Email, and to its attached file.For example, this document comprises MP3 montage or other electronic document.In step 104, Email is sent to the addressee, and at first arrive e-mail server.In step 106, server is analyzed annex.For example, file extension has determined that (for example extension name " .mp3 " is expressed as mp3 file for the type of file; Expansion " .mpg " is expressed as mpeg file; Expansion " .avi " is expressed as avi file etc.).Usually, a such file has a letter head of describing content.What should be noted is that for he adds the purpose of summary by oneself, the user can copy this document from Web, and renames this document.If another source that file can be on Web, server are analyzed this letter head and are checked an index that create or that be pre-created when operation.In addition, server is also checked file at watermark or other unique identifier of an embedding, or uses the content (for example Waveform Matching, fingerprint recognition) of another process identifier file, to find a listed copy.If can obtain this document, use the pointer an of URL or another alternative this document that the Email body is sent to the addressee in step 110 so from another source.URL or other pointer are the source on the attached identical file identification Web of transmit leg.If server can not be located a source for file in Web, so e-mail forward to the addressee who arranges by transmit leg.

For watermark and fingerprint (also being called " spallation "), be the known technology that is used to identify the audio or video content.Watermark is the signal or the pattern that are embedded in the audio or video content.Even complete possibility, watermark also is difficult to be removed.Under common Voice ﹠ Video operation (for example D/A and A/D conversion, filtering or compression), keep watermark.Usually, only can could detect watermark by appropriate software.The user that is authorized to that watermark makes it possible to discern content, its source, transmission path, its author, owner, the right to use, watermark content becomes possibility.Yet watermark influences content itself, and fingerprint does not touch content, is the only identifier of fingerprint but created one for that section content.Usually, use a kind of spallation algorithm that is applied to digital content that fingerprint is calculated.

Best, use about the information of analyzed file index and upgrade, and preferably in a background processes, upgrade server.For example, if server can not be found a source on the Web, server can temporarily remain on file in the ultrahigh speed buffer so, and it correspondingly upgrades index.In addition, if the pointer in the corresponding source on the existing sensing Web of index neither one, and one of discovering server so also makes an addition to the latter index of server.

More than can be an automatic process to substituting of file pointer.In addition, transmit leg also can show to server: if possible, he will wish to allow server substitute annex with a pointer, so that save bandwidth.If selected alternative selection, then the service provider can provide the discount of collecting service fee to this concrete transmit leg.In addition, recipient or addressee also can show to his/her service provider: if possible,, preferably adopt pointer as annex, rather than content, so that reduce bandwidth and memory space.

Also can embody another aspect of the present invention by the software on the PC that resides in the end user.This software and local mailer cooperation.When detecting annex of Email, this software attempts to judge whether the content information of annex can obtain from Web publicly, if can obtain from Web publicly, then locatees a URL or one group of URL.For example, this software goes to judge an address of content information via search engine of a browser command, and a tabulation of Return URL.When discovered, from Email dismounting annex down, and substituted one or more URL leave user's PC at Email before.

Fig. 2 is the structure chart that a system 200 among this present invention on the one hand has been described.System 200 comprises an Email subscriber's PC202.PC202 has one makes the user can be via the email application 204 of data network 206 send Emails, and an e-mail server 208 that leads to addressee 210.PC202 also comprises instead of software 212 and a browser 214.The Email that the user created that instead of software 212 is analyzed by PC202 is to judge whether to the attached electronic document of Email to be sent is arranged.If find also to have identified annex, then software 212 order browsers 214 are got in touch with a search engine 216, and identical electronic document can be in the source on the data network 206 with understanding.Suppose that search engine 216 has an obtained index of listing source 218, wherein source 218 has the copy of former state that a user has attached to the electronic document of email body.Browser 214 obtains from a pointer in search engine 216 source of returning 218 (for example, a URL), and notice software 212.Then, software 212 is peeled off annex from Email, or cuts off the binding between Email and the annex, and substitutes this pointer.Next, can be sent to addressee 210 to Email at any time.When receiving Email, the addressee opens Email via embedded pointer, and the copy of search file.
