Responsive to determining the received credentials for verification from the first user match the credentials of record, the method sends the received transit information to the first user.

Description

BACKGROUND

The present invention relates generally to handling of shipments and more particularly to encryption based handling of shipment information.
Typically, when shipping a product through a carrier network, the condition of the product is not known until the product reaches a destination of a recipient and the product is inspected for damage. Upon inspection, external damage to the product is visible to the recipient and the recipient can report the damage to the carrier prior to accepting the shipment. Reporting the damage to the carrier prior to accepting the delivery of the product results in the carrier being held responsible for the damages. However, certain products, such as computer servers, are susceptible to damage due to shock or vibrations. Damage caused by shock or vibration is typically not visible due to the damage being internal rather than external. As a result, the carrier may not be held responsible for any damages and the sending party has to cover the cost of repairs for the internal damage to the product potentially caused by the carrier.

SUMMARY

Embodiments of the present invention include a method, computer program product and computer system for handling information of shipments. A computer-implemented method includes: receiving, by one or more processors, transit information from a first data logger, wherein the first data logger is associated with a first shipment; identifying, by one or more processors, a first user based on an identifier associated with the first shipment; querying, by one or more processors, the first user for credentials for verification; and responsive to determining the received credentials for verification from the first user match the credentials of record, sending, by one or more processors, the received transit information to the first user.

DETAILED DESCRIPTION

Example embodiments in accordance with the present invention will now be described in detail with reference to the drawing figures. FIG. 1A is a functional block diagram illustrating a data processing environment. The distributed data processing environment includes server computer 102, client device 104, and electronic device 114A through electronic device 114N connected over network 106.
Server computer 102 may be a desktop computer, a laptop computer, a tablet computer, a specialized computer server, a smartphone, or any other computer system known in the art. In certain embodiments, server computer 102 represents a computer system utilizing clustered computers and components that act as a single pool of seamless resources when accessed through network 106, as is common in data centers and with cloud computing applications. In general, server computer 102 is representative of any programmable electronic device or combination of programmable electronic devices capable of executing machine readable program instructions and communicating with other computer devices via a network.
Shipment handling program 108 located on server computer 102 has the ability to initiate a transport process for shipments 112A through 112N provided by a sender. Shipment handling program 108 can receive package information and billing information for each of the shipments 112A through 112N. Shipment handling program 108 can create an identifier for each shipment 112A through 112N and associate data logger 116A though 116N with an identifier for each shipment 112A through 112N, respectively. Subsequently, shipment handling program 108 initializes the transport process for each shipment 112A through 112N.
Shipment handling program 108 has the ability to receive encrypted transit information for shipments 112A through 112N, where the encrypted transit information is accessible by a sender of shipments 112A through 112N (i.e., a user of client device 104). Shipment handling program 108 can receive transit information from data logger 116A through 116N when each shipment 112A through 112N reaches a touch point in the transport process. Shipment handling program 108 can identify a customer (i.e., a user of client device 104) based on the associated identifier for each shipment 112A through 112N and query the customer for credential verification. Upon determining credentials for verification match credentials on record, shipment handling program 108 decrypts the transit information for each shipment 112A through 112N utilizing an encryption key associated with the received verified credentials. Shipment handling program 108 can send the transit information for each shipment 112A through 112N to client device 104, where the customer can view the transit information.
Client device 104 may be a desktop computer, a laptop computer, a tablet computer, a specialized computer server, a smart phone, or any programmable electronic device capable of communicating with server computer 102 via internal network 106. In general, client device 104 represents any programmable electronic device or combination of programmable electronic devices capable of executing machine readable program instructions and communicating with other computing devices via a network, such as network 106.
User interface 110 provides an interface between a user of client device 104 and shipment handling program 108. User interface 110 may be a graphical user interface (GUI) or a web user interface (WUI) or a command line interface and can display text, documents, web browser windows, user options, application interfaces, and instructions for operation, and includes the information (such as graphic, text, and sound) a program presents to a user and the control sequences the user employs to control the program. User interface 110 may also be mobile application software that provides an interface between a user of client device 104 and shipment handling program 108. Mobile application software, or an “app”, is a computer program designed to run on smart phones, tablet computers and other mobile devices. User interface 110 enables a user of client device 104 to provide credentials for verification to shipment handling program 108 and to view transit information for shipments 112A through 112N.
Shipments 112A through 112N each represent packages being sent to multiple recipients, not illustrated in FIG. 1. Each shipment 112A through 112N includes electronic device 114A through 114N, respectively. Electronic device 114A through 114N each provide a communication channel for transferring transit information recorded by data logger 116A through 116N for each shipment 112A through 112N. Each electronic device 114A through 114N communicates with data logger 116A through 116N and user interface 118A through 118N, respectively. Each data logger 116A through 116N has the ability to record various transit information including, for example, shock, vibrations, degree of tilt, temperature, light exposure, barometric pressure, moisture, longitudinal and latitudinal shift, and humidity. In this embodiment, data logger 116A through 116N are located internally on shipment 112A through 112N, respectively. In another embodiment, data logger 116A through 116N are located on electronic device 114A through 114N, where each electronic device 114 includes data logger 116 and user interface 118.
User interface 118A through 118N provides an interface between a package handler and shipment handling program 108. User interface 118A through 118N may be a graphical user interface (GUI) or a web user interface (WUI) or a command line interface and can display text, documents, web browser windows, user options, application interfaces, and instructions for operation, and includes the information (such as graphic, text, and sound) a program presents to a user and the control sequences the user employs to control the program. In this embodiment, each user interface 118A through 118N displays an identifier for each shipment 112A through 112N, respectively. The identifier can be, for example, a tracking number that is scanned at each touch point during the shipment process. Each user interface 118A through 118N can also display a transit bill for each shipment 112A through 112N.
In general, network 106 can be any combination of connections and protocols that will support communications among server computer 102, client device 104, and electronic device 114A through 114N. Network 106 can include, for example, a local area network (LAN), a wide area network (WAN), such as the internet, a cellular network, or any combination of the preceding, and can further include wired, wireless, and/or fiber optic connections. In one embodiment, shipment handling program 108 can be a web service accessible via network 106 to the user of client device 104. In another embodiment, shipment management program 108 may be operated directly by a user of server computer 102.
FIG. 1B is a functional block diagram illustrating one embodiment of a data logger and user interface on a shipment, in an embodiment in accordance with the present invention.
In this embodiment, shipment 112A represents an enclosed pallet containing an assembled piece of computer equipment, such as, a server rack. Electronic device 114A, located on the exterior of shipment 112A, includes an external display with user interface 118A. User interface 118A can display information such as an airway bill, a tracking number, an address of a recipient, an address of a sender, and transit information provided by data logger 116A. In this embodiment, data logger 116A is located internally on shipment 112A and records various transit information to which the assembled piece of computer equipment of the enclosed pallet experiences. Data logger 116A is connected to electronic device 114A and user interface 118A allows for the carrier company to obtain transit information from data logger 116A at various touch-points during the transportation of shipment 112A.
FIG. 2 is a flowchart depicting one embodiment of a shipment handling program for initiating a shipment of a package, in accordance with the present invention. As depicted, the method includes receiving (202) package information, receiving (204) billing information, creating (206) an identifier for the package, receiving (208) data logger information, determining (210) to associated the data logger with the identifier, and initializing (212) shipment of the package. In one embodiment, the method is conducted by shipment handling program 108.
The method may commence by receiving (202) package information. Shipment handling program 108 can receive package information including dimensions, weight, content, and handling instructions. The package information can also include whether the package includes a data logger for recording transit information. In this embodiment, shipment handling program 108 receives the package information from a user of client device 104, where the user of client device 104 is considered a sender of the package. The user of client device 104 sends the package information to shipment handling program 108 while preparing the package for shipment. In another embodiment, shipment handling program 108 receives the package information via a user interface (e.g., user interface 118A) on an electronic device (e.g., electronic device 114A) located on the package.
The method may continue by receiving (204) billing information. Shipment handling program 108 can receive billing information including a customer identification number, a destination address, a return address, and account information for a customer. In this embodiment, the customer identification number found in the billing information identifies the customer to whom the package is associated. Shipment handling program 108 can include a credential verification for the customer identification number found in the received billing information to ensure account security for the customer. Additional, the customer identification number also allows for shipment handling program 108 to query the customer for credential verification when sending transit information for the package. In this embodiment, shipment handling program 108 receives the billing information from a user of client device 104, where the user of client device 104 is considered a sender of the package. The user of client device 104 sends the billing information to shipment handling program 108 while preparing the package for shipment. In another embodiment, shipment handling program 108 receives the billing information via a user interface (e.g., user interface 118A) on an electronic device (e.g., electronic device 114A) located on the package.
The method may continue by creating (206) an identifier for the package. An example of an identifier for the package includes a bar code, a quick response (QR), a data matrix, a micro PDF, or any other unique identifier known in the art. In this embodiment, shipment handling program 108 utilizes a tracking number embedded in a bar code as an identifier for the package. The tracking number is unique to the package and provides an identification to the package being shipped.
The method may continue by receiving (208) data logger information. The data logger information identifies a specific data logger unique to the package. A data logger located on an electronic device on the package can record various transit information including shock, vibrations, degree of tilt, temperature, and humidity. However, data logger information can include a serial number identifying a specific data logger associated with the package. The serial number prevents a handler of the package from replacing the data logger on the package being shipped without the customer's knowledge. In this embodiment, shipment handling program 108 receives the data logger information from a user of client device 104. The user of client device 104 sends the data logger information to shipment handling program 108 subsequent to selecting the data logger which is going to record the transit information during the shipment of the package. In another embodiment, shipment handling program 108 receives the logger information via a user interface (e.g., user interface 118A) on an electronic device (e.g., electronic device 114A) with the data logger (e.g., data logger 116A).
The method may continue by determining (210) to associate the identifier for the package with the received data logger information. In this embodiment, shipment handling program 108 associates the identifier package with the received data logger information to prevent tampering of the transit information being recorded. A customer accessing the information of a particular package based on the created identifier for the package is ensured that the data logger shipment handling program 108 associates with the package is the same data logger from which transit information is received. In one example, shipment handling program 108 stores the association of the identifier for the package along with the received data logger information for the duration of the shipment. In another example, shipment handling program 108 stores the association of the identifier for the package along with the received data logger information for a predefined duration of time. As a result, shipment handling program 108 can maintain a history of the created identifiers for the packages.
The method may continue by initializing (212) shipment of the package. In this embodiment, shipment handling program 108 releases the package with the data logger to the carrier for shipment. Shipment handling program 108 can send a customer associated with the received billing information a notification that the shipment of the package has initialized and data logger information identifying the data logger from which transit information will be produced during the duration of the shipment of the package.
FIG. 3 is a flowchart depicting one embodiment of a shipment handling program for managing transit information of packages, in accordance with the present invention. As depicted, the method includes receiving (302) transit information from a data logger, identifying (304) a customer based on the associated identifier for the package, querying (306) the customer for credential information, determining (308) whether the credentials match, decrypting (310) the transit information based on an encryption key associated with the verified credentials, and sending (312) the decrypted transit information to the customer. In one embodiment, the method is conducted by shipment handling program 108.
The method may commence by receiving (302) transit information from a data logger. Shipment handling program 108 receives transit information from the data logger when the package reaches a touch point in the logistical setting of the carrier. A touch point represents any point in the logistical setting of the carrier where the identifier for the package is scanned, for example, when the package reaches a centralized hub or when the package is placed on a final delivery truck. Shipment handling program 108 can also continuously receive transit information from the data logger in the form of a live stream. For example, if the package is located on an airplane, shipment handling program 108 can connect with the data logger through an inflight Wi-Fi internet connection and continuously receive transit information from the data logger for the duration of the flight. Shipment handling program 108 can continuously receive the transit information and notify the customer if the data logger registers an event. An event can include, for example, a humidity level exceeding a particular percentage value (e.g., 70%) or a degree of tilt exceeding a particular threshold (e.g., 20°).
In this embodiment, the transit information shipment handling program 108 receives is encrypted, while the package identifier is not encrypted. The transit information remains encrypted until the customer associated with the package identifier verifies credentials, upon which an encryption key on the credentials decrypts the transit information for the customer to view. Encrypting the transit information prevents the carrier from altering the values in the transit information being receive from the data logger. In another embodiment, shipment handling program receives transit information that is decrypted, where the transit information does not require an encryption key from the credentials of the customer.
The method may continue by identifying (304) a customer based on the associated identifier for the package. In this embodiment, shipment handling program 108 receives the package identifier along with the transit information from the data logger. Shipment handling program 108 can utilizes the package identifier to retrieve billing information. The customer identification number found in the billing information identifies the customer to whom the package is associated.
The method may continue by querying (306) the customer for credential verification. Shipment handling program 108 utilizes the customer identification number to query the associated customer for credential verification in order to view the transit information. Shipment handling program 108 can send a notification prompting a window in the user interface (i.e., user interface 110) of the client device (i.e., client device 104) associated with the customer. In this embodiment, credentials of a customer include a customer identification number and a password for the account associated with the customer.
The method may continue by determining (308) whether the credentials match. In the event the credentials match (“yes” branch, 308), the method may continue by decrypting (310) the transit information based on an encryption key associated with the verified credentials. In the event the credentials do not match (“no” branch, 308), the method may query (306) the customer for credential verifications. In one embodiment, shipment handling program 108 can include an attempt limit for receiving credentials for verifications of a customer. For example, if the credentials do not match for three attempts by the customer, shipment handling program 108 can send a notification to the customer providing credentials, to contact the carrier to resolve the issue.
The method may continue by decrypting (310) the transit information based on an encryption key associated with the verified credentials. In this embodiment, shipment handling program 108 utilizes an encryption key embedded in the password of the verified credentials to decrypt the transit information. The encryption key is a piece of information (i.e., a parameter) that determines the functional output of a cryptographic algorithm or cipher. Without a key, the algorithm would produce no useful result. The encryption key transforms the ciphertext of the transit information into readable plaintext. The carrier does not have the ability to view the decrypted content prior to sending the decrypted transit information to the customer (312).
The method may continue by sending (312) the decrypted transit information to the customer. In this embodiment, shipment handling program 108 sends the decrypted transit information to a client device (i.e., client device 104) associated with the customer. The customer can view the transit information in a user interface (i.e., user interface 110) on the client device and determine whether to take an action in the shipment process of the package. For example, if a particular event in the transit information is registered by the data logger, the customer has the ability to see the date and time when the event occurred. Shipment handling program 108 can receive the specific date and time of the registered event by the data logger and send the registered event and customer's information to the carrier for investigation.
