In one example, each recipient of interest is issued an article that embodies unique sender authentication information that is identifiable by corresponding location information such as column and row identifiers. In both an apparatus and method, when the sender of an electronic message wants to send a message to a recipient of interest, the sender sends the electronic message and both location information and corresponding desired sender authentication information located at the coordinate identified by the location coordinate information. If the sent desired sender authentication information matches authentication information found on the article, the sender of the message is trusted.
RELATED CO-PENDING APPLICATION This is a continuation-in-part of U.S. patent application entitled METHOD AND APPARATUS FOR SECURELY PROVIDING IDENTIFICATION INFORMATION USING TRANSLUCENT IDENTIFICATION MEMBER, having Ser. No. 10/748,523, filed on Dec. 30, 2003, having as inventors Chiviendacz et al. and owned by instant Assignee.
FIELD OF THE INVENTION The invention relates generally to methods and apparatus for providing authentication of an electronic message sending entity, and more particularly to methods and apparatus that employ soft tokens or hard tokens for authenticating senders of electronic messages such as email.
BACKGROUND OF THE INVENTION Ensuring that a sent email message or other electronic message has been sent by a sender that can be trusted, also referred to as being authentic, helps ensure against theft of important information by unscrupulous parties and can help limit spam and phishing. Phishing is a form of Internet scam that usually involves the mass sending of emails which appear to be from a legitimate organization such as a bank or other financial institution or other organization. These emails often direct the recipient to a fraudulent website or form where he or she is tricked into divulging personal or financial information. An alternative phishing scam may not ask for such information but, upon entering the URL, execute a download of a keystroke-logging program that lets the phisher harvest information from the recipient's machine. The information can then be used for identity theft and fraud.
In an apparently unrelated field, translucent cards are known such as plastic cards that contain a semi-transparent picture or pattern that when visually evaluated does not appear to connote any particular information. However, when the translucent card is held over a display with a corresponding background filter pattern, the combination of the pattern on the card with the background pattern on the display screen combine to present a visually recognizable message or word such as the word �sorry� or �you're a winner�. These are static messages which are not unique to any user and typically include only a single message. Such plastic cards may be used for example to see if a holder has won a prize. The card for example may be mailed in the mail to members of a population. Those recipients then go to a web page identified on the translucent card or otherwise indicated in the mailing information to see if they have won a prize. However, such plastic cards do not provide multi-factor authentication, are not user specific, do not include multiple messages and typically include static messages.
DETAILED DESCRIPTION OF THE DRAWINGS FIG. 1 is a block diagram illustrating one example of a system for securely providing identification information in accordance with one embodiment of the invention;
DETAILED DESCRIPTION OF A PREFERRED EMBODIMENT OF THE INVENTION Briefly, a method for providing electronic message authentication employs an article (also referred to as a member or token), such as a card, sticker, or any other suitable article, that includes sender authentication information and location information, such as row and column headings. In one example, each recipient of interest is issued an article that embodies sender authentication information that is identifiable by corresponding location information such as column and row identifiers. When the sender of an electronic message wants to send a message to a recipient of interest, the sender sends the electronic message and both location information and corresponding desired sender authentication information located at the location identified by the location information. This includes data representing the location and authentication information (such as an index to, a reference to, the location information or authentication information itself, or any suitable representation thereof). The recipient may then, in one embodiment, look on their article (e.g. card) at the corresponding location and see if the sent desired sender authentication information matches the sender authentication information located on the article (also referred to as expected sender authentication information). If a match occurs, then the recipient trusts the sender of the message. The recipient need not send back any information to the sender. As such, a simple card or other article may be used to authenticate a sender of a message to thwart phishing, or other sender authentication problems. Other examples will be recognized by those of ordinary skill in the art.
Once a visually revealed identifier is presented to a user, a user enters the visually revealed identifier through a user interface where it is compared to an expected identifier. If the entered identifier matches the expected identifier, proper authentication is indicated and a recipient may be granted access to a device, application, or process or other desired right (or submitted data is accepted�e.g. such as a vote). In addition, a list of revoked translucent identification members may also be maintained to prevent compromise due to theft or loss of translucent identification members. The list may be stored in any suitable location and updated by a service provider, translucent identification member issuer or any suitable entity. Since the translucent identification members do not require electronics to generate random numbers, the cost of such translucent identification members may be quite low and their reliability may also be relatively high since they are not susceptible to moisture or other damage typically associated with smart cards.
FIGS. 10 and 11 illustrate another embodiment of the operation of the system after the issuance of the translucent identification member has occurred. As shown in block 1000, the method includes requesting and obtaining recipient specific information 32 such as previously described with reference to FIG. 5. Once the translucent identification member 14 has been printed or manufactured, it is then provided to the recipient by hand or through mail or any other suitable technique as shown in block 1002. As shown in block 1004, a bank server of a bank determines if a recipient has requested authentication, such as to a logon request. If a request has been received, a web page may be sent requesting entry of the recipient information 32 including the password and the translucent identification member serial number 44 as a first level of a multi-factor authentication process as shown in block 1006. This may be done for example through the screen shown in FIG. 5. As shown in block 206, the bank server determines whether the entered recipient specific information 32 and password and translucent identification member serial number 44 are correct for example by passing along the information to the translucent identification member authenticator 24. If the first authentication level passes, the method includes, as shown in block 1010, displaying the visual filtering pattern 44 that when visually combined with the one or more obscured identifiers 38 on the translucent identification member 14, reveals only one of the one or more obscured identifiers as the appropriate identifier to be entered for the current session or transaction. The bank server may then, through the web server, request entry of the revealed identifier 700 as selectively revealed through the filtering pattern displayed on the display by providing the screen as shown in FIG. 6. This is shown in block 1010. In response to the request, the translucent identification member authenticator 24 receives the revealed one time use identifier 700 and compares the received identifier to a corresponding expected ID determined for example by the visual filter generator or authenticator 24. This is shown in block 1012. Given the �filter�, the user's data entry and stored information about that user, the authenticator can validate whether the user entered correct data or not (either on its own or by passing it to a �server�). If the desired identifier is generated before requesting it from the user, the system also generates the right filter to reveal the pre-determined identifier (all before presenting to the user). Alternatively, if the user is provided with a pattern (the filter) and then the system validates the identifier that the user entered with the identifier that would have resulted from that pattern, a desired identifier need not be picked ahead of time and the �filter generator�, therefore does not require knowledge of anything else. The data representing the visually revealed identifier (e.g., the date itself, an encrypted form thereof or other suitable data, may also be received using a device other than the device on which the visual filtering pattern is displayed. For example, the identifier may be revealed on a screen of one device and a handheld device or non-handheld device may be used to enter and send the visually revealed identifier to another device or system that checks whether there is a match.
In addition, in this embodiment there need not be recipient specific information if the system does not require it, as the sender authentication information may be generated either independent from or based on recipient specific information if desired. This may occur when the recipient signs up for the service. In addition, as used herein, location information includes the information, for example, sent with a message or indexed by a message sent by the sender which indicates which sender authentication information on the article 1800 that the recipient is to verify. For example, location information need not be row and column information, but may merely be the terms such as �upper left corner�, �lower left corner�, �third from the right�, or any other suitable information to notify the recipient which sender authentication information on the article is to be used as the authentication information for the given session, transaction or other communication. Alternatively, the sender authentication information can be a pointer to a location that contains the sender authentication information, such as, for example, a universal resource locator (URL) that points to the sender authentication information for the given session, transaction or other communication. Additionally, the location information can be a pointer to a location that contains the actual location information, which in turn indicates where to look on the article for the sender authentication information for the given session, transaction or other communication. In another embodiment, the location information is a visual filtering pattern.
Referring also to FIG. 21, a specific example of a message and associated sender authentication information and location information is shown as 2100. In a particular embodiment, also referring to FIG. 18, the message is appended with sender authentication information and in particular numbers �98413� and coordinate information of �A2, E4, F1, H4, J2�. As such, the sending unit sends the electronic message along with both desired sender authentication information and desired location information as shown. The user then uses the article 1800 and looks, for example, at coordinate location A2 and sees the number 9, looks at the location coordinate E4 and sees the number 8, looks at the coordinate location F1 and sees the number 4, looks at the coordinate location H4 and sees the number 1, and looks at the coordinate location J2 and sees the number 3. If the user sees the same sender authentication information on the article 1800 as was sent by the sending unit, then the recipient trusts the sender as being an authentic message sender. In this example, the sender authentication information visually represents sender authentication information that is identifiable by location coordinate information in the form of rows and columns. However, it will be recognized that rows and column format need not be used and as such the cells as shown need not be employed. For example, if objects are used as opposed to letters and numbers, the objects may be located in upper left, upper right, middle or any other suitable location of the article and the sender authentication information, which could be the object can be sent such as in the form of a graphic or other suitable object, and the coordinate location information may actually be words that might read �upper left corner�. Any other suitable coordinate location information or sender authentication information may also be used.
