PRIORITY CLAIM

The present application is a U.S. national stage application (under 35 USC §§ 371) of PCT international application PCT/IB2018/052479 having an international filing date 10 Apr. 2018, which claims priority from Indian non-provisional application no 201741013732 filed with the Indian Patent Office on 18 Apr. 2017.

DESCRIPTION OF THE INVENTION

Technical Field of the Invention

The present invention relates to a system and method for storing digital data with enhanced privacy. More particularly, the invention relates to a stand-alone device that works independently without being connected to any communication channel. The device does not support Wi-Fi, Bluetooth or any other media of communication. Further, the invention is designed to work independently and will not connect or communicate with any other systems or devices for the purpose of information security enabled with multiple access levels to access data or information of varying complexity.

Background of the Invention

We often interact with data or information of varying complexities. Usually, systems employ a single password authentication method irrespective of data or information complexity thereby making the data vulnerable for misuse. Existing devices or systems are enabled with Bluetooth, Wi-Fi or other communication channels to facilitate communication with various other systems or devices. A major risk of accessing authenticated information or data in an unauthorized manner always prevails in such systems. Integrity of data is a fundamental requirement for any storage device or system to build and maintain a moral and commercial reputation.

The patent application WO0152023A9 titled “Method and system for secure personal authentication credentials data over a network” discloses a method and system for registering storing and managing personal data for use over a network, and for allowing users to register for, link to and log onto third party websites wherein the invention securely transmits authentication credentials data for automatic login at third party web sites. However, the major disadvantage is that the system communicates with third party websites leading to breach in (high risk and vulnerable) confidentiality, integrity and accessibility of data or information.

The patent application CN101577622A titled “Method for controlling access to shared component of leveled partition” discloses a method for controlling access to shared component of leveled partition. Further, the application discloses about unified and coordinated access control to maintain confidentiality, integrity and availability of a species-level partition. However, the invention does not reveal any information regarding the accessibility of data based on its complexity, importance, usefulness, severity, criticality and vulnerability.

The patent application U.S. Pat. No. 7,721,345B2 titled “Data security system and method” discloses a data security system and method, wherein the data is extracted and controlled on a granular basis, utilizing security protocols. Further, this document discloses an information processing system for securely storing data and rebuilding that data in the presence of an adequate security clearance, wherein the system determines the level of security clearance. The document also discusses about a method for securing data on a single personal computer. However, the major disadvantage is that the system allows multiple security control options like password, passphrase, multiple choice questions and answers, initial, intermediate and subsequent security clearance routines and biometric security routines like voice, fingerprint, signature, eye or retina scan which may permit unauthorized users to access the stored data in any of the disclosed methods.

The patent application U.S. Pat. No. 8,086,675B2 titled “generating a fingerprint of a bit sequence” discloses a method of generating a fingerprint of a bit sequence which includes determining a relative occurrence frequency of each bit combination of a set of bit combinations in the bit sequence, wherein the set of bit combinations comprises all possible non-redundant sub-sequences of bits having at least one bit and at most a preset maximal number of bits. However, the invention does not disclose the presence of any reminder that can be set and used for all the authentication data.

The patent application U.S. Pat. No. 8,550,339B1 titled “Utilization of digit sequences for biometric authentication” discloses systems and methods for implementing a sequence of fingerprints for biometric authentication as a sequence of fingerprints is more difficult to fraudulently circumvent than a single finger or thumb print. However, this invention may be connected to multiple systems or devices through various communication channels which may lead to reduced confidentiality, integrity and accessibility of the stored data or information.

Hence, there exists a need for a system or device that ensures confidentiality, integrity and accessibility of stored data or information that would be well received in the art.

SUMMARY OF THE INVENTION

The present invention overcomes the drawback in the prior art and provides system for storing digital data with enhanced privacy in an efficient and precise manner.

In a preferred embodiment of the invention, the system comprises a portable storage device which is based on confidentiality, integrity and accessibility for information security. The device stores data independently, without being connected to any communication channel. The storage device further comprises a display window to display a main menu and a credential menu. An access layer is provided in the storage device to enter different combinations and sequence of fingerprints. Further, the storage device also includes a non-USB power port to charge the battery of the storage device.

In a preferred embodiment of the invention, the storage device comprises a touchscreen keypad configured to enter the data manually, the memory in the storage device configured to store entered data. Further, the storage device further provides low battery alerts and reminder alerts.

Thus, the invention provides a storage device that ensures confidentiality, integrity and accessibility of stored data or information.

Further, the advantage of the present invention is that data/credentials or information stored on the device can only be accessed by the owner of the device. This feature of the invention ensures security of the stored data. The data will be erased off if any other person other than the owner of the data tries to access the device/data.
