Our invention is more closely related to the ATM cash box and the goods trunk used in railways. BACKGROUND OF THE INVENTION The portable lockers are used to store clothes, documents, ornaments during transportation from one location to another location. The present day lockers do not provide sufficient security in transit mode. There is a need to provide security for the lockers so that the valuables related to the authorized person is safe during transit [4-9]. The security sector is experiencing diversification as it has never seen before with the advancement in the digital technology. Everyday, the amount of security to safeguard valuables things is ever increasing. This has intrigued us to study the need by reviewing the reliability of already existing systems and look into the possibility of better systems that are smarter and secure. The conventional locker systems include a mechanical key which is operated manually to open the locker system. These kind of physical key, which is operated manually, can be opened using a similar replica of the key. Also, the lock is susceptible for breakage and leads to loss of material stored in the locker. To increase the security, digitally secured and single password based digital lockers are also available in the market. These electronic key once shared is easy for breaking or can be broken using all possible combination which pose as hard problem in computational science and further it is susceptible to opening the locker and the security of the locker is lost. If the physical key is misplaced or stolen then it is difficult to prove authentication to the user. Similarly, there are many advanced solutions such as electronic lock systems, mobile verification, password verification and other safety mechanisms to increase security in portable lockers for allowing only authorized personal to access their lockers. These lockers are usually used as personal locker and provide security to the locker related to that person. Thus, the materials kept inside the locker is owned by the person, who operates the locker. Thus, the concept of reusing the same locker for another person will be difficult with this kind of locker. Re-usability of these lockers are limited with the sense of owning a locker. At the same time, when somebody has to use the same locker, then the person has to share the password or the physical key which leads to loss of security for the locker once revealed or duplicated. In urban, people use multiple keys of same lockers. It is an advantageous for the people who arrive late night or come early to open the locked house or room. The life of people is easier with the advent of technology. Earlier, a person, if decides to withdraw money for personal use, had to go to bank during the bank timings, then fill up the withdrawal form, wait for the clearance and stand in a queue to collect from the cashier [1-3]. With the automation, the entire process has been automated and a person can withdraw money from any of the automated teller machine (ATM) without waiting for bank to be opened for withdrawal operation. A person with authentic debit card can withdraw money from a list of ATM connected to the central banking server. When many people draw from a single ATM machine, the machine has to be filled again with cash by the bank. The bank hires a security agency to transport the cash from the bank to the ATM in box. The bank which relies on the security agency assumes that the cash being carried from the bank to the ATM is secure. Generally cash is brought to ATM centers in conventional mechanical key lockers. In recent times, we have come across the news that the ATM cash is being stolen by the security guard deployed by the security agency. When this kind of incidence happens regularly, the assurance of the security agency is decremented. With huge amount of cash being transported in box, the loyalty of the security is depreciated against indulging in stealing the cash. There should be a way to overcome the stated problem faced by the bank and providing additional security. The mailbox used for transportation of general public goods in railways face similar kind of threat, being misplaced or stolen during transit period. No proper security is provided for the valuables being transported. In such case, there is a threat to the valuables during the transit period. Hence, we emphasize for the security of the valuable items being transferred from a location to another location. OBJECTIVE OF INVENTION Our primary objective is providing security to the portable lockers and additional security with the help of sensors to alert the user. SUMMARY OF THE INVENTION The present invention provides a re-usable and secured portable locker system. The system includes a portable locker, transport medium for transporting the locker, A GPS system for tracking the locker, at least one communication device for issuance of instructions to the user and a Geo-tagging security tool configured to enable the locker to open within a preset geographical coordinates. In an embodiment, the present invention provides a method for accessing a portable locker comprising the steps of configuring the geographical coordinates of the destination location where the box has to be opened. The locker is transported to the destination. Once, the portable locker reaches the destination, then the user needs to request for a one time password (OTP) for accessing the locker. After the user requests for the password, the verification of predefined geographical coordinates of the user location for enabling the locker to open is checked. If the location matches with the preset geographical coordinates, then the portable locker sends a one time password to the authenticated user’s registered mobile number using which the user can access the locker. In order to track the locker during the transit time or in case of theft of the locker, a command is sent by the registered mobile number to get the GPS coordinates of the locker. Thus, the locker location can be identified with the details received by the registered mobile number.

The invention generally relates to portable lockers which are used to transport goods
and documents. Our invention is more closely related to the ATM cash box and the
goods trunk used in railways.
BACKGROUND OF THE INVENTION
The portable lockers are used to store clothes, documents, ornaments during
transportation from one location to another location. The present day lockers do not
provide sufficient security in transit mode. There is a need to provide security for the
lockers so that the valuables related to the authorized person is safe during transit
[4-9]. The security sector is experiencing diversification as it has never seen before
with the advancement in the digital technology. Everyday, the amount of security to
safeguard valuables things is ever increasing. This has intrigued us to study the
need by reviewing the reliability of already existing systems and look into the
possibility of better systems that are smarter and secure. The conventional locker
systems include a mechanical key which is operated manually to open the locker
system. These kind of physical key, which is operated manually, can be opened
using a similar replica of the key. Also, the lock is susceptible for breakage and leads
to loss of material stored in the locker. To increase the security, digitally secured and
single password based digital lockers are also available in the market. These
electronic key once shared is easy for breaking or can be broken using all possible
combination which pose as hard problem in computational science and further it is
susceptible to opening the locker and the security of the locker is lost. If the physical
key is misplaced or stolen then it is difficult to prove authentication to the user.
Similarly, there are many advanced solutions such as electronic lock systems,
mobile verification, password verification and other safety mechanisms to increase
security in portable lockers for allowing only authorized personal to access their
lockers. These lockers are usually used as personal locker and provide security to
the locker related to that person. Thus, the materials kept inside the locker is owned
by the person, who operates the locker. Thus, the concept of reusing the same
locker for another person will be difficult with this kind of locker. Re-usability of these
lockers are limited with the sense of owning a locker. At the same time, when
somebody has to use the same locker, then the person has to share the password or
the physical key which leads to loss of security for the locker once revealed or
duplicated. In urban, people use multiple keys of same lockers. It is an
advantageous for the people who arrive late night or come early to open the locked
house or room.
The life of people is easier with the advent of technology. Earlier, a person, if decides
to withdraw money for personal use, had to go to bank during the bank timings, then
fill up the withdrawal form, wait for the clearance and stand in a queue to collect from
the cashier [1-3]. With the automation, the entire process has been automated and a
person can withdraw money from any of the automated teller machine (ATM) without
waiting for bank to be opened for withdrawal operation. A person with authentic debit
card can withdraw money from a list of ATM connected to the central banking server.
When many people draw from a single ATM machine, the machine has to be filled
again with cash by the bank. The bank hires a security agency to transport the cash
from the bank to the ATM in box. The bank which relies on the security agency
assumes that the cash being carried from the bank to the ATM is secure. Generally
cash is brought to ATM centers in conventional mechanical key lockers. In recent
times, we have come across the news that the ATM cash is being stolen by the
security guard deployed by the security agency. When this kind of incidence
happens regularly, the assurance of the security agency is decremented. With huge
amount of cash being transported in box, the loyalty of the security is depreciated
against indulging in stealing the cash. There should be a way to overcome the stated
problem faced by the bank and providing additional security.
The mailbox used for transportation of general public goods in railways face similar
kind of threat, being misplaced or stolen during transit period. No proper security is
provided for the valuables being transported. In such case, there is a threat to the
valuables during the transit period. Hence, we emphasize for the security of the
valuable items being transferred from a location to another location.
OBJECTIVE OF INVENTION
Our primary objective is providing security to the portable lockers and additional
security with the help of sensors to alert the user.
