Field of the Embodiments

This invention relates to digital currency and crypto currency (collectively,“digital currency”) protection and security in a cloud-based environment. In particular, the invention allows digital currency data to be stored in a cloud environment whereby it is inaccessible to any third party.

Background of the Embodiments

With the advent of the internet, cyber security and data privacy is a growing global concern in today’s world. Information technology and electronic discovery advances in a variety of industries, including the legal industry have compounded the issue. The United States and many foreign countries have enacted strict and stringent requirements on data privacy and security. Global entities and multinational corporations have struggled to comply with local data privacy laws. Data privacy laws define how companies and individuals must store and manage computer data. However, the laws are complex and sometimes the laws of one jurisdiction are in direct conflict with the laws of another jurisdiction. This has caused companies to give much thought as to how and where it stores their protected data. Because of the evolution of technology, companies are migrating away from managing and storing data internally, and opting instead to store data with a third party. The third party provider provides the physical infrastructure and maintains the data for a large number of customers. This scenario is generally known as the "cloud" or a virtual storage system. Such cloud-based systems are used by many companies, but each is maintained by a single cloud service provider or "cloud vendor".

The development of the cloud has introduced many new challenges for companies.

Customers are unclear as to what jurisdiction contains their inactive digital data (i.e. data at rest), since a cloud customer does not know where a cloud vendor maintains its actual physical infrastructure. Other challenges involve data security. Cloud environments can be

compromised by hackers or by a company’s internal employees ultimately leading to an organization’s data being accessed or transferred. If the data is sensitive, such as personally identifiable information (“RP”), the company may be required to make a mandatory disclosure to its customers. In some cases, the company is not aware of such an invasion, and thereby may not make the disclosure they are required to make. In addition, a cloud vendor may go offline or go out of business, thereby creating a potential situation where a subscriber cannot access its own data. The present invention solves many of these and other challenges.

The present invention relates to a cloud-based system including the creation of a system which causes computer data to be redundant and jurisdiction independent. In the present application, a data file is segmented and encrypted wherein each data file segment is striped across multiple cloud service providers. Thus, in the event each cloud service provider maintains physical storage in a different jurisdiction, then each encrypted segment will be at rest in a different jurisdiction. Therefore, each encrypted segment contains no readable data on its own, and must be reassembled with its other segments before the whole can be decrypted. Only once the segments from different jurisdictions are assembled can it be decrypted and read. The disclosed system enables a data file to be jurisdictionally independent until it is reassembled, and once the data is reassembled will it be able to be governed. The present application enables a company to subscribe to many cloud vendors, and not have to worry about their data at rest. For example, during the legal discovery process, a company can choose the jurisdiction for data production simply by reassembling its data in that jurisdiction.

Description of the Preferred Embodiments

The preferred embodiments of the present invention will now be described with reference to the drawings. Identical elements in the various figures are identified with the same reference numerals.

Reference will now be made in detail to each embodiment of the present invention. Such embodiments are provided by way of explanation of the present invention, which is not intended to be limited thereto. In fact, those of ordinary skill in the art may appreciate upon reading the present specification and viewing the present drawings that various modifications and variations can be made thereto.

FIG. 1 shows the process flow of data through the cloud-based system of the present application. The process commences with a native data file, the data file is encrypted and broken into segmented parts, and the segmented data file is then forwarded to multiple cloud storage providers located in multiple jurisdictions. A client (or multiple clients) connects to a Storage Director Appliance or Software Application through a Multi -Protocol Connector. The multi protocol connector may be via a web browser through the Internet. The Storage Director Appliance or Application has the ability to locally store a cached file in a local cache storage.

The file is processed by a processing engine where it is encrypted and separated into“n” parts. Each of the parts are passed on to the Cloud Queue Engine, which transmits and deposits the segmented parts to multiple Cloud Providers located in multiple legal jurisdictions. When the file is requested by an authorized user, The Cloud Queue Engine retrieves a copy of each of“n” parts, downloads them to the Storage Director Appliance or Application, and processes the Segmented parts to re-create the original encrypted file. The encrypted file is decrypted, and the native file becomes available to the user.

FIG. 2 shows a flow chart diagram that describes the process of taking a native file and securely storing it in one of multiple cloud vendors located in more than one jurisdiction. To reassemble the file, the process is simply reversed. In step 1, local or native data is received from a Client and ready for processing. In step 2, the file and location data are written to the Storage Director module Lookup Table. In step 3, the file is processed by the Processing Engine, where it is encrypted. The encrypted file is then broken into multiple data blocks, and each block is assigned a unique name or identifier. In step 4, the Storage Director module Lookup table is updated with the block name of each data block and the total Quantity of blocks that were created from the original encrypted file. In steps 5 the data blocks are Forwarded and moved to storage providers as per a preset algorithm as instructed by the Cloud Queue Engine or Module. In step 6, the blocks are forward and moved to one of multiple cloud storage providers which are located in multiple jurisdictions as instructed by the Cloud Queue Engine or Module. The blocks are stored at cloud providers located in different jurisdictions. In step 7, the Storage Director module lookup table is updated with the data location of each block at each Cloud Provider. In FIG. 3, a graphical representation of the data flow is shown. FIG. 3 also illustrates how data blocks are securely and redundantly stored across Cloud Providers in“n” jurisdictions.

Once a native data file is encrypted and broken into data blocks by the Storage Director

Appliance or Application, the Cloud Queue Engine or module distributes the blocks to“n” Cloud Providers in“n” legal jurisdictions. Each data block is written to two or more Cloud Providers, which“stripes” the data across multiple providers in varying jurisdictions. If a given Cloud Provider is compromised by going offline and unavailable, the Cloud Queue Engine can still retrieve the data blocks from another Cloud Provider. In addition, if a given Cloud Provider is compromised by a hacker or unauthorized user, the data blocks that may have been compromised are of no value to the hacker, because the hacker will only be in possession of encrypted blocks, and not any entire file.

The present embodiments relate to systems and methods for secure data storage in a multi-vendor cloud environment in a manner that prevents the third party cloud provider from being able to access or be in possession of complete data files. The computer or device that creates the source data distributes only a portion of a data file to each of a plurality of cloud storage providers. The source computer or device maintains a lookup table and is able to re assemble the data. Each storage provider only maintains part of each data file, and therefore is never in possession of any complete data file(s). The source computer or device can retrieve each portion of the file from multiple cloud providers, whereby the portions are re-assembled into the complete data file by using the lookup table. The system allows for large amounts of data to be stored across a plurality of third party cloud storage providers in a manner that prevents any third party from having access to any complete file. The data is distributed globally among a plurality of cloud storage providers. No single cloud provider has access to any complete file, as each file is broken into Encrypted segments or data blocks and only one Data block is sent to each cloud provider. Each cloud provider is in a different physical location across multiple jurisdictions. As a result, the file does not exist at rest in any one jurisdiction, thus is not subject to legal and/or regulatory requirements of any single jurisdiction while it is stored in a multi-vendor cloud environment.

The system ensures that any data file stored in a multi-vendor cloud environment in this manner cannot be subject to the laws governing production of, privacy of, or protection of data in any jurisdiction. In another embodiment, a system and method for securely sharing data files by using a multi-vendor cloud environment in a manner that prevents any third party from being able to access or be in possession of the original source data file is taught. The computer or device that creates the source data splits each file into multiple segments. Each segment is then encrypted using an encryption key defined by the user. Each of the encrypted fragments are then distributed to multiple cloud properties whereby only a portion of the fragments of the source data file is stored to any one of a plurality of cloud storage providers. The source computer or device maintains a pointer file that contains a lookup table and is able to re-assemble the data if it knows the encryption key and has access to the same cloud properties. Each storage provider only maintains part of each data file, and therefore is never in possession of any complete data file(s). Any computer or device that has possession of the pointer file, knows the encryption key, and has access to the cloud provider storage can retrieve each portion of the file from multiple cloud providers, whereby the portions are downloaded, decrypted using the user generated encryption key stored in the pointer file, and re-assembled into the complete data file by using the lookup table. The system allows for large amounts of data to be stored across a plurality of third party cloud storage providers in a manner that prevents any third party from having access to any complete file. The data is safe from being exploited or hacked by any third party, since even if all cloud providers are breached, the data cannot be re-assembled without the encryption key and the lookup table.

In this embodiment, the method comprises; a source data file is created, the source data file is split into fragments; an encryption key is created by the user; each fragment is encrypted using the encryption key; the fragments are distributed in multiple cloud storage providers, whereby no single cloud storage provider is in possession of all fragments; a pointer file is created that stores the location of each fragment; the pointer file is stored locally, and the original file is deleted. The user is able to open the pointer file, enter the encryption key, and

authenticate to the cloud storage providers. Each fragmented is transferred from the cloud storage providers to the local computer. The fragments are re-assembled locally on the computer.

In another embodiment, a system and method for securely sharing data files by using a multi-vendor cloud environment in a manner that prevents any third party from being able to access or be in possession of the original source data file is taught. The computer or device that creates the source data splits each file into multiple segments. Each segment is then encrypted using an encryption key defined by the user. Each of the encrypted fragments are then distributed to multiple cloud properties whereby only a portion of the fragments of the source data file is stored to any one of a plurality of cloud storage providers. The source computer or device maintains a pointer file that contains a lookup table and is able to re-assemble the data if it knows the encryption key and has access to the same cloud properties. The pointer file can be freely shared with other users using any data transmission method, including email, copy/paste, etc. Each storage provider only maintains part of each data file, and therefore is never in possession of any complete data file(s). Any computer or device that has possession of the pointer file, knows the encryption key, and has access to the cloud properties can retrieve each portion of the file from multiple cloud providers, whereby the portions are downloaded, decrypted using the user generated encryption key stored in the pointer file, and locally re assembled into the complete data file. The system allows for large amounts of data to be stored across a plurality of third party cloud storage providers in a manner that prevents any third party from having access to any complete file, unless the source user shares the pointer file, encryption key, and access to the cloud properties. The data at rest is safe from being exploited or hacked by any third party, since even if all cloud providers are breached, the data cannot be re assembled without the pointer file, encryption key, and access to a complete set of fragments.

In this embodiment, the method comprises: a source data file is created; the source data file is split into fragments; an encryption key is created by user #1; each fragment is encrypted using the encryption key; the fragments are distributed in multiple cloud storage providers, whereby no single cloud storage provider is in possession of all fragments; a pointer file is created that stores the location of each fragment; the pointer file is stored locally, and the original file is deleted. The pointer file is shared with user #2. User #2 is able to access the fragments stored at the cloud storage providers; User #2 has knowledge of the encryption key; User #2 is able to open the pointer file, enter the encryption key, and authenticate to the cloud storage providers. Each fragmented is transferred from the cloud storage providers to the local computer of user #2. The fragments are re-assembled locally on the computer of user #2.
