scanning, by an image capturing unit of the device, at least one of eyeballs of the user trying to access the device, wherein the scanning results in generation of a current scanned eyeball image;

matching, by the device, the current scanned eyeball image with a previously scanned eyeball image of an authorized user of the device and plurality of scanned eyeball images of plurality of other users;

identifying, by the device, the user, based on the matching,

as the authorized user of the device when the current scanned eyeball image matches with the previously scanned eyeball image, and

as a guest user when the current scanned eyeball image is matched with at least one of the plurality of scanned eyeball images;

performing, by the device, based on the identifying, at least one of,

providing a pre-defined content access permission to the authorized user; and

determining an age of the guest user based on processing of the current scanned eyeball image relative to the at least one of the plurality of scanned eyeball images, and

providing a restricted content access permission to the guest user based on the age determined for the guest user and permission policy associated with the age of the guest user; wherein determining the age of the guest user comprises:

computing an axial length and back scattering, from the current scanned eyeball image, of the user's eye identified as the guest user, wherein the axial length of the user's eye is computed using a calibration technique of autorefractors, and wherein the back scattering is computed using a tomographic retinal imaging technique;

comparing the axial length and the back scattering with pre-stored age comparison index, wherein the pre-stored age comparison index comprises mapping between age and corresponding axial length and the back scattering; and

determining the age of the guest user based on the comparing.

2. The method as claimed in claim 1 , wherein the permission policy comprises at least one of disabling of one or more contents, enabling of the one or more contents, disabling one or more functionalities of the device, enabling the one or more functionalities of the device, access time of the one or more contents, and access location of the one or more contents.

3. The method as claimed in claim 1 , wherein the previously scanned eyeball image of the authorized user and the plurality of scanned eyeball images of the plurality of other users are pre-stored in an image database of the device.

4. The method as claimed in claim 1 , wherein the authorized user with the predefined content access permission is provided with complete access of one or more contents stored in the device and one or more functionalities associated with the device.

5. The method as claimed in claim 1 , wherein the guest user with the restricted content access permission is provided with selective access of one or more contents stored in the device and one or more functionalities associated with the device.

6. A device for providing content access permission to a user of the device, the device comprising:

an image capturing unit to scan at least one of eyeballs of the user trying to access the device, wherein the scanning results in generation of a current scanned eyeball image;

a processor; and

a memory communicatively coupled to the processor, wherein the memory stores processor-executable instructions, which, on execution, causes the processor to:

match the current scanned eyeball image with a previously scanned eyeball image of an authorized user of the device and plurality of scanned eyeball images of plurality of other users;

identify, the user, based on the matching,

as the authorized user of the device when the current scanned eyeball image matches with the previously scanned eyeball image, and

as a guest user when the current scanned eyeball image is matched with at least one of the plurality of scanned eyeball images;

perform, based on the identification, at least one of,

provide a pre-defined content access permission to the authorized user; and

determine an age of the guest user based on processing of the current scanned eyeball image relative to the at least one of the plurality of scanned eyeball images, and

provide a restricted content access permission to the guest user based on the age determined for the guest user and permission policy associated with the age of the guest user; wherein the device determines the age of the quest user by:

 computing an axial length and back scattering, from the current scanned eyeball image, of the user's eye identified as the guest user, wherein the axial length of the user's eye is computed using a calibration technique of autorefractors, and wherein the back scattering is computed using a tomographic retinal imaging technique;

 comparing the axial length and the back scatterinq with pre-stored age comparison index, wherein the pre-stored age comparison index comprises mapping between age and corresponding axial length and the back scattering; and

 determining the age of the quest user based on the comparing.

7. The device as claimed in claim 6 , wherein the permission policy comprises at least one of disabling of one or more contents, enabling of the one or more contents, disabling one or more functionalities of the device, enabling the one or more functionalities of the device, access time of the one or more contents, and access location of the one or more contents.

8. The device as claimed in claim 6 , wherein the device comprises an image database for storing the previously scanned eyeball image of the authorized user and the plurality of scanned eyeball images of the plurality of other users.

9. The device as claimed in claim 6 , wherein the authorized user with the pre-defined content access permission is provided with complete access of one or more contents stored in the device and one or more functionalities associated with the device.

10. The device as claimed in claim 6 , wherein the guest user with the restricted content access permission is provided with selective access of one or more contents stored in the device and one or more functionalities associated with the device.

11. A non-transitory computer-readable storage medium including instructions stored thereon that when processed by at least one processor cause a device to perform operations comprising:

scanning at least one of eyeballs of the user trying to access the device, wherein the scanning results in generation of a current scanned eyeball image;

matching the current scanned eyeball image with a previously scanned eyeball image of an authorized user of the device and plurality of scanned eyeball images of plurality of other users;

identifying, the user, based on the matching,

as the authorized user of the device when the current scanned eyeball image matches with the previously scanned eyeball image, and

as a guest user when the current scanned eyeball image is matched with at least one of the plurality of scanned eyeball images;

performing, based on the identifying, at least one of,

providing a pre-defined content access permission to the authorized user; and

determining an age of the guest user based on processing of the current scanned eyeball image relative to the at least one of the plurality of scanned eyeball images, and

providing a restricted content access permission to the guest user based on the age determined for the guest user and permission policy associated with the age of the guest user; wherein determining the age of the quest user comprises:

computing an axial length and back scattering, from the current scanned eyeball image, of the user's eye identified as the guest user, wherein the axial length of the user's eye is computed using a calibration technique of autorefractors, and wherein the back scattering is computed using a tomographic retinal imaging technique;

comparing the axial length and the back scattering with pre-stored age comparison index, wherein the pre-stored age comparison index comprises mapping between age and corresponding axial length and the back scattering; and

determining the age of the quest user based on the comparing.

12. The medium as claimed in claim 11 , wherein the permission policy comprises at least one of disabling of one or more contents, enabling of the one or more contents, disabling one or more functionalities of the device, enabling the one or more functionalities of the device, access time of the one or more contents, and access location of the one or more contents.
