System for improving data security
A system allows a user to store his personally identifiable information (PII) on a personal device. 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.

adjust the personally identifiable information to produce anonymized data; and
generate an identifier for a ledger storing the anonymized data.
9. The system of claim 1 , wherein the hardware processor is further configured to:
receive a request to lock out the user;
receive the token indicating a second request for the personally identifiable information after receiving the request to lock out the user; and
in response to receiving the request to lock out the user, reject the second request for the personally identifiable information.
10. A method for protecting personally identifiable information, the method comprising:
generating, by a hardware device, a public encryption key of the hardware device;

generating, by a hardware processor separate from the hardware device, a public encryption key of the hardware processor, wherein the public encryption key of the hardware processor is generated based on the public encryption key of the hardware device;
encrypting, by the hardware, the personally identifiable information to produce first encrypted personally identifiable information using at least the public encryption key of the hardware processor;
receiving, by the hardware processor, the first encrypted personally identifiable information from the hardware device;
decrypting, by the hardware processor, the first encrypted personally identifiable information to produce the personally identifiable information;
generating a token representing the personally identifiable information;

establishing, by the hardware device, a connection with the hardware processor;
in response to receiving an indication of receipt of the token from the hardware processor, encrypting, by the hardware device, the personally identifiable information to produce second encrypted personally identifiable information; and
communicating, by the hardware device, the second encrypted personally identifiable information to the hardware processor.
11. The method of claim 10 , further comprising deleting, by the hardware processor, the public encryption key of the hardware processor in response to a determination that the public encryption key of the hardware processor has been active for a period of time that exceeds a threshold.
12. The method of claim 10 , further comprising:
receiving, by the hardware processor, from a second hardware device, a public encryption key of the second hardware device;
