From the background information supplied by the inventors, news correspondents obtained the following quote: “Users provide their information (e.g., name, address, telephone number, email address, social security number, etc.) in a variety of contexts (e.g., mortgage applications, credit card applications, financial account applications, air travel ticket orders, medical office visits, etc.). If this information were exposed to or taken by a malicious user, then the malicious user would be able to use this information to impersonate the users to conduct undesired or unwanted transactions.”
Supplementing the background information on this patent, NewsRx reporters also obtained the inventors’ summary information for this patent: “Users provide information (e.g., name, address, telephone number, email address, social security number, etc.) in a variety of contexts (e.g., mortgage applications, credit card applications, financial account applications, air travel ticket orders, medical office visits, etc.). If this information were exposed to or taken by a malicious user, then the malicious user would be able to use this information to impersonate the users to conduct undesired or unwanted transactions.
“In conventional systems, the users have very little control over this information. The users provide their information to a provider to gain access to goods or services from the provider. The provider maintains the information (e.g., on a server). If that server were to be breached by a malicious user, the information would be exposed to the malicious user. Additionally, some providers even sell the information to other providers, often unbeknownst to the users. This sale and movement of the information further exposes the information to malicious users and lessens the control that the users have over such information.
“This disclosure contemplates an unconventional system for securing information (e.g., a user’s personally identifiable information (PII)). Generally, the system allows the user to store his PII on a personal device, such as a smartphone. When a third party wants to access the user’s PII (e.g., to update the PII or to retrieve the PII), a notification will be presented to the user on the personal device seeking consent to the access. The notification may inform the user as to what information is being requested and which entity is requesting the access. The requested access will be denied unless the user consents to the access. In this manner, the user is given control over the dissemination of his PII. Additionally, the system alters or adjusts the PII that is stored in third-party servers so that even if these servers are breached, the user’s actual PII is not exposed.
“According to an embodiment, a system includes a device of a user and a token handler separate from the device. The device receives personally identifiable information the user and encrypts the personally identifiable information to produce first encrypted personally identifiable information. The token handler receives the first encrypted personally identifiable information from the device of the user, decrypts the first encrypted personally identifiable information to produce the personally identifiable information, generates a token representing the personally identifiable information, and receives the token indicating a request for the personally identifiable information. The device receives consent from the user to provide the personally identifiable information in response to the request for the personally identifiable information, in response to receiving the consent from the user, encrypts the personally identifiable information to produce second encrypted personally identifiable information, and communicates the second encrypted personally identifiable information to the token handler.
“When PII is to be stored or updated, the system first seeks consent from the user for the PII store or update. If the user grants consent, then the system stores the PII in the user’s personal device or updates the PII stored in the user’s personal device. The system then generates a token representing the PII. The token can be presented at a later time to redeem or access the PII, subject to the user’s consent. Even if the token were taken by a malicious user, it would not be possible for the malicious user to determine the user’s actual PII from the token. In this manner, the security of the PII is improved over conventional systems.”
The claims supplied by the inventors are:
“1. A system for protecting personally identifiable information, the system comprising: a hardware device configured to: generate a public encryption key of the hardware device; receive personally identifiable information of a user; and a hardware processor separate from the hardware device, the hardware processor configured to generate, based on the public encryption key of the hardware device, a public encryption key of the hardware processor; wherein the hardware device is further configured to encrypt the personally identifiable information to produce first encrypted personally identifiable information using at least the public encryption key of the hardware processor; wherein the hardware processor is further configured to: receive the first encrypted personally identifiable information from the hardware device; decrypt the first encrypted personally identifiable information to produce the personally identifiable information; generate a token representing the personally identifiable information; and receive the token indicating a request for the personally identifiable information; wherein the hardware device is further configured to: establish a connection with the hardware processor; after determining that the hardware processor has received the token indicating the request for the personally identifiable information, prompt the user for consent to provide the personally identifiable information; in response to receiving the consent from the user, encrypt the personally identifiable information to produce second encrypted personally identifiable information; and communicate the second encrypted personally identifiable information to the hardware processor.
