[0102] and thereby restricting external forces such as shock, impact, fire, water, etc from damaging the storage device

[0102] , The layers made from material such as, polycarbonate is temperature resistant, and flame retardant / self-extinguishing. Similarly, ABS has high tensile strength and is very resistant to physical impacts and chemical corrosion, which allow the finished plastic to withstand heavy use and adverse environmental conditions.

[0102] (or as used herein, storage unit

[0102] ). Also, the housing

[0204] encapsulates the storage device

[0102] , Also, all of the components / units of the system

[0200] are assumed to be connected to each other unless otherwise indicated below. As shown in the FIG. 2 all units shown within the system should also be assumed to be connected to each other. Also, in FIG. 2 only a few units are shown, however, the system

[0200] may comprise multiple such units or the system

[0200] , The damage may be intentional or unintentional. The damage includes, but is not limitedto, the user device may be immersed in water or other liquids, chemicals, etc., being exposed to conditions like fire, subject to extreme stress such as under stone or rock.

[0042] The memory unit

[0202] is adapted to be integrated on the user device. In an implementation of the present disclosure, the memory unit

[0202] may be operably connected with the user device. In another implementation of the present disclosure, the memory unit

[0202] may be part of the memory of the user device. The memory unit

[0202] may perform data backup in the event of damage. In another implementation, the memory unit

[0202] may be integrated in a printed circuit board (PCB) of the user device. The memory unit

[0202] is a micro / nano secure digital (SD) card which can be easily installed on the user device. The micro / nano SD card may be installed on the PCB of the user device and the PCB is connected with other components of the user device.

[0043] The data backup includes, but may not be limited to, call logs, instant messaging (IM) logs, browsing history, notes, downloaded files, ambient audio of a predetermined period of time, photos and videos of a predefined number. The IM logs may be a record of messages that take place over an instant messaging (IM) platform. The IM logs keep tracks of important discussions or maintains a record for compliance. The ambient audio refers to noise that may be picked from the background of the user device. In one example, the predetermined period of time may be determined by a system operator.

[0200] , an administrator of the system

[0200] , and / or a manufacturer of the system

[0200] , and the like. For example, the predetermined period of time to record the ambient audio may be 24 hours.

[0202] comprises the storage device

[0102] , The storage device

[0102] is adapted to store the data backup. The data backup stored in the storage device

[0102] is encrypted according to a predefined protocol. The predefined protocol comprises techniques based on a public key and private key pair for encrypting the data for storage in the storage device

[0102] , The public key is used for encrypting data to protect data by using codes to prevent unauthorised access. The process of encryption includes converting a readable data into unreadable data. The public key cannot be used to decode the data. The data may be decrypted by the private key only. The predefined protocol may be a post-quantum cryptography method. The post-quantum cryptography refers to cryptographic algorithms that may be secure from decryption by quantum computers. The post-quantum cryptography includes but may not be limited to forming algorithmsbased on hash functions, error-correcting codes, lattice-based cryptography codes, multivariate polynomial cryptography, and the like. The encryption based on hash functions refers to taking input data and transform the data into fixed-length strings of characters. The input to the hash function may be of any length but the output is always of fixed length. The cryptography based on error correcting codes involves encoding data in a way that even if some parts of the data may get corrupted, the original data can be recovered. The multivariate polynomial cryptography is a type of public-key cryptography that uses multivariate polynomials. The multivariate polynomials are resistant to quantum attacks. In one example, once the data backup is encrypted, the user may not be able to access the data backup.

[0045] The memory unit

[0202] further comprises the housing

[0204] , The housing

[0204] encapsulates the storage device

[0102] , In an implementation of the present disclosure, the storage device

[0102] may be coupled to the memory unit

[0202] , In another implementation the storage device

[0102] may be a part of the memory unit

[0202] , The storage device

[0102] may be one of an industrial and automotive secured digital (SD) card, an ultra-high speed (UHS) card, an application performance class, a Secure Digital Standard Capacity (SDSC), a secure digital extended capacity (SDXC), a Secure Digital Ultra Capacity (SDUC), a mini SD card, a micro SD card and a nano SD card.

[0046] In an implementation of the present disclosure, a processing unit of the user device may clean the backup data at predefined intervals of time. The predefined intervals of time may be defined by the system operator. The cleaning includes removing old data and adding new data to the backup. For example, if the predetermined number of photos to be stored in the storage device

[0102] is defined as the latest 100 photos. Once a new set of 100 photos is added to the memory of the user device, the storage device

[0102] may clean and remove the 100 photos to add the new set of photos.

[0047] The housing

[0204] is adapted to at least partially restrict an external force from acting on the storage device

[0102] , The housing

[0204] comprises a plurality of layers

[0104] , The plurality of layers

[0104] are configured to cover the storage device

[0102] , The plurality of layers

[0104] is made up of damage proof material. The damage proof material may protect the storage device

[0102] from shock, impact, fire, water, electromagnetic blasts, radiation and the like. These pluralities of layers form a strong protective cover for the storage device

[0102] and thereby restricting external forces such as shock, impact, fire, water, etc from damaging the storage device

[0102] , The layers made from material such as, polycarbonate is temperature resistant, and somewhat flameretardant / self-extinguishing. Similarly, ABS has high tensile strength and is very resistant to physical impacts and chemical corrosion, which allow the finished plastic to withstand heavy use and adverse environmental conditions. However, it is to be noted, there is no such material which can fully protect a device from all kinds of damages. Therefore, the present disclosure by using the layers as described above is able to at least partially restrict the damages to the user device.

[0048] In one example, each layer from the plurality of layers

[0104] is made from a material selected from a group consisting of polycarbonate, acrylonitrile butadiene styrene (ABS), fiberglass, reinforced plastic (FRP), polyethylene, carbon fiber, carbon fiber composites, rubber, elastomer, metal alloy, kevlar, rubberized fabric, honeycomb structure, polyurethane (PU), ceramic, armour, polyimide, refractory material, ablative material, lead, concrete, and combinations thereof. These pluralities of layers form a strong protective cover for the storage device

[0102] and thereby restricting external forces such as shock, impact, fire, water, etc from damaging the storage device

[0102] , The layers made from material such as, polycarbonate is temperature resistant, and somewhat flame retardant / self-extinguishing. Similarly, ABS has high tensile strength and is very resistant to physical impacts and chemical corrosion, which allow the finished plastic to withstand heavy use and adverse environmental conditions.

[0049] Further, after the data backup is stored in the storage device

[0102] , the memory unit

[0202] is adapted to decrypt the encrypted data based on the public key and private key pair for the data backup to be accessible to the user. The private key is to decrypt data that was encrypted with the corresponding public key. The decryption may be performed by an authorised entity. The authorised entity may perform decryption using some commands or execute certain code or scripts to run decryption algorithms. The authorised entity includes but may not be limited to an original equipment manufacturer (OEM) approved by a regulatory agency, such as Telecom Regulatory Authority of India (TRAI).

[0050] Referring to FIG. 3, an exemplary method flow diagram

[0300] for data backup, and recovery in an event of damage to a user device, in accordance with exemplary implementations of the present disclosure is shown. In an implementation the method

[0300] is performed by the system

[0200] , Further, in an implementation, the system

[0200] may be present in a server device to implement the features of the present disclosure. Also, as shown in FIG. 3, the method

[0300] starts at step

[0302] ,

[0051] At step

[0304] , the method comprises selecting a data to be stored in the storage device

[0102] , by a processing unit of the user device. The processing unit is a part of the user device and may store information for data backup and recovery by the storage device

[0102] , The damage includes but is not limited to the user device may be immersed in water or other liquids, chemicals, etc., being exposed to conditions like fire, subject to extreme stress such as under stone or rock. The data refers to information including the call logs, the IM logs, the browsing history, the notes, the downloaded files, the ambient audio of the predetermined period of time, the photos and the videos of the predefined number. This data may be selected by the user by using the interface of the user device and browsing the user device to locate and select the data.

[0052] At step

[0306] , the method comprises encrypting, by the processing unit, the data based on a predefined protocol. The processing unit may run certain commands or application on the user device to encrypt the selected data using the predefined protocol, which comprises techniques based on a public key and private key pair for encrypting the data for storage in the storage device

[0102] , The predefined protocol may be a post-quantum cryptography method. Cryptography is a process of hiding transmitted information by the sender such that it may be read only by the intended recipient. The post-quantum cryptography also known as Quantum -Resistant Cryptography (QRC), focuses on developing cryptographic algorithms and protocols able to stand up to quantum computing power. The public key cryptography algorithms which are used currently, are sufficient protection today, however, using a quantum computer, a hacker would be able to break the algorithms or reduce the strength of the symmetric crypto keys and crypto hashes in minutes. Post-Quantum Cryptography uses a new set of Quantum Resistant Algorithms, created by researchers and tested by industry standard bodies. The present disclosure uses post-quantum cryptography algorithms for encrypting the data for greater safety and protection as described above. The PQC algorithms use a larger key size, for example, Advanced Encryption Standard (AES) with keys greater than today's 128-bit keys, [his way, post-quantum cryptography is a defense against potential cyberattacks from quantum computers. Further, the public key is used in PQC algorithms for encrypting data to protect data by using codes to prevent unauthorised access. The process of encryption includes converting a readable data into unreadable data by using a combination of numerical computations that appear incomprehensible to the untrained eye. Techniques like mathematical concepts and algorithms are used to make the transferred data difficult for others to decode. The public key cannot be used to decode the data. The data may be decrypted by the private key only. Further, the post-quantum cryptography includes but may not be limited to forming algorithms based on hash functions, error-correcting codes, lattice-based cryptography codes, multivariate polynomial cryptography, and the like. The encryption based onhash functions refers to taking input data and transforming the data into fixed-length strings of characters. The input to the hash function may be of any length but the output is always of fixed length. The fixed length of the output is because a hash is a deterministic hexadecimal number. This means that no matter how many characters the input has, the hash will always be the same number of characters. The cryptography based on error correcting codes involves encoding data in a way that even if some parts of the data may get corrupted, the original data can be recovered. The multivariate polynomial cryptography is a type of public-key cryptography PKC) that uses multivariate polynomials. This type of public key cryptography is considered as one of the major types of PKCs that could resist potentially even the powerful quantum computers of the future. It is based on the computational problem of finding the roots of a system of multivariate polynomials over a finite field.

[0053] Next at step

[0308] , the method comprises storing, by the processing unit, in the storage device

[0102] , the encrypted data. The processing unit may select the storage device

[0102] on the user interface of the user device and transfer the encrypted data to the storage device

[0102] using user interface-based actions, like dragging. The storage device

[0102] is integrated with the memory unit

[0202] of the user device. The storage device

[0102] in the memory unit

[0202] may be covered by the plurality of layers

[0104] , The plurality of layers

[0104] refers to a damage proof material. The damage proof material may protect the storage device

[0102] from shock, impact, fire, water, electromagnetic blasts and radiation. In one example, each layer from the plurality of layers

[0104] is made from a material selected from a group consisting of polycarbonate, acrylonitrile butadiene styrene (ABS), fiberglass, reinforced plastic (FRP), polyethylene, carbon fiber, carbon fiber composites, rubber, elastomer, metal alloy, kevlar, rubberized fabric, honeycomb structure, polyurethane (PU), ceramic, armour, polyimide, refractory material, ablative material, lead, concrete, and combinations thereof.

[0054] In an implementation of the present disclosure, the backup data may be cleaned at predefined intervals of time. The predefined intervals of time may be defined by the system operator. In an example, the system operator may be one of: a user of the system

[0200] , an administrator of the system

[0200] , and the like. The cleaning includes removing old data and adding new data to the backup. For example, if the predetermined number of photos to be stored in the storage device

[0102] is defined as the latest 100 photos. Once a new set of 100 photos is added to the memory of the user device, the storage device

[0102] may clean and remove the 100 photos to add the new set of photos.

[0055] Further, after the data backup is stored in the storage device

[0102] , the data backup may be decrypted based on the public key and private key pair, for the data backup to be accessible to the user. The private key is to decrypt data that was encrypted with the corresponding public key. The decryption may be performed by an authorised entity. The authorised entity includes but may not be limited to an original equipment manufacturer (OEM) approved by a regulatory agency.

[0056] The method terminates at step

[0310] ,

[0057] Referring to FIG. 4, an exemplary method for data backup, in accordance with exemplary implementations of the present disclosure, is shown.

[0058] At step

[0402] , a data is generated in the memory of the user device. The data includes, but not limited to, the call logs, the IM logs, the browsing history, the notes, the downloaded files, the ambient audio of the predetermined period of time, the photos and the videos of the predefined number.

[0059] Next, at step

[0404] , a data backup is selected from the generated data. The data backup may include a set of critical call log data, critical IM logs, critical notes, critical download files, and the like. The data backup may be defined by a user of the user device. In another example, the processing unit of the user device may be configured to identify the data backup from the generated data at the user device. The data backup may be selected by the processing unit of the user device. In an implementation of the present disclosure, the storage device

[0102] may be configured to store the data backup at predefined time intervals from the generated data at the user device. The predefined time period may be defined by the user of the user device, the system operator, the system

[0200] , and the like.

[0060] Next at step

[0406] , the selected data backup is encrypted. In an implementation, the encryption method is the post-quantum cryptography. Once the selected data backup is encrypted, the user may not be able to access the data backup. The data backup may be decrypted by the original equipment manufacturer (OEM). The OEM may decrypt the data backup based on an approval of a regulatory authority. In another example, the approval may be of a lawful agency. The process of decryption by the OEM includes the OEM to access the encrypted data backup stored in the storage device

[0102] , Before decrypting, the OEM may verify the integrity of the data backup. The verification may include checking the digital signature of the lawful agency. Further,the OEM may retrieve a decryption key. Based on the decryption key, the OEM initiates the decryption process.

[0104] are made of a material selected from the group consisting of polycarbonate, acrylonitrile butadiene styrene (ABS), fiberglass, reinforced plastic (FRP), polyethylene, carbon fiber, carbon fiber composites, rubber, elastomer, metal alloy, kevlar, rubberized fabric, honeycomb structure, polyurethane (PU), ceramic, armour, polyimide, refractory material, ablative material, lead, concrete, and combinations thereof. The plurality of layers

[0104] protects the storage device

[0102] from damages including but not limited to shock, impact, fire, water, electromagnetic blasts and radiation to avoid the backup data from getting destroyed.

[0062] At step

[0410] , the backup data is cleaned at predefined intervals of time. The predefined intervals of time may be defined by the system operator. In an example, the system operator may be one of: a user of the system

[0200] , an administrator of the system

[0200] , a manufacturer of the system

[0200] , and the like. The cleaning includes removing old data and adding new data to the backup. For example, a set of official call data may be stored in the storage device

[0102] , A new set of official call data is added to the user device every day, the official call log data may be cleaned every day to update the call data in the storage device

[0102] from the user device and the old set of official call data may be removed.

[0063] The data may be recovered from the storage device

[0102] based in an event of damage to the user device without any damage to the data stored in the storage device

[0102] ,

[0102] , The instructions when executed further cause the processing unit to encrypt the data based on a predefined protocol. The instructions when executed further cause the processing unit to store the encrypted data in the storage device. The storage device

[0102] is integrated with a memory unit

[0202] in the user device, the memory unit

[0202] comprising a housing

[0204] comprising a plurality of layers

[0104] , and encapsulating the storage device
