Abstract

Consumers may utilize computing devices to assist in the purchase and/or loyalty process, and in particular, the consumer may utilize a PDA to facilitate the purchase and/or loyalty process. During the purchase and/or loyalty process, the consumer may need to insure that any content downloaded or used in association with the PDA is secure in how it is collected, assembled, and delivered to the PDA device. This system and method secures the data from its source to when it is actually viewed or used by the authorized user. The PDA may have direct access to an Internet web site portal that offers secure personal content from a content provider, such as, for example, an on-line banking or financial institution. Using the web site portal, the content provider may offer personal or confidential data, such as financial information, to PDA users in a secure (e.g., encrypted) environment. The exemplary system and method may establish a PDA portal link to the web site for collecting specified information for a user and transmitting the information to the remote device. To receive the information, the PDA contacts the portal and establishes a connection, authenticates itself to the network, and allows the user to complete secured transactions or transmissions over the network.

Claims

1. A PDA portal system which facilitates securing content from a source to a PDA, said system comprising:

receiving a signal from said PDA indicating a portion of said content to be at least one of refreshed and downloaded;

identifying said PDA;

interrogating said source containing said content to determine secure content is included in said content;

connecting to an encryption device, which is configured to;

establish a secure connection to said source using a negotiated encryption key, receive encrypted content which is an encrypted portion of first content, decrypt said encrypted content, interrogate said encrypted content to identify an embedded link, isolate said embedded link, re-encrypt said first content with an encryption key of a PDA user, receive second content based on said embedded link, and transmit said embedded link, said first content, and said second content to said PDA portal;

receiving said embedded link, said first content, and said second content from said encryption device; and

,

transmitting said embedded link, said first content, and said second content to said PDA for storage when said content has been collected from at least one of said source, wherein said first content and said second content remains encrypted on said PDA.

2. A method for facilitating secure collection of content from a source using a PDA portal, said method comprising:

receiving a signal from a PDA indicating said content to be one of refreshed and downloaded;

identifying said PDA;

interrogating said source containing said content to determine secure content is included in said content;

connecting to an encryption device, which is configured to;

establish a secure connection to said source using a negotiated encryption key, receive encrypted content which is an encrypted portion of first content, decrypt said encrypted content, interrogate said encrypted content to identify an embedded link, isolate said embedded link, re-encrypt said first content with an encryption key of a PDA user, receive second content based on said embedded link, and transmit said embedded link, said first content, and said second content to said PDA portal;

receiving said embedded link, said first content, and said second content from said encryption device; and

,

transmitting said embedded link, said first content, and said second content to said PDA for storage when said content has been collected from at least one of said source, wherein said first content and said second content remains encrypted on said PDA.
