Securing shipment information accessed based on data encoded in machine-readable data blocks

A system for securing access to shipment information, the system comprising:

• a processor;
• a memory;
• a module that is stored in the memory and that is configured, when executed by the processor, to perform a method comprising:
• restricting and redirecting access to shipment information, the access based on data encoded in a machine-readable data block in a packing list, the data including a first access token, by:
• receiving a request from a client computing system and based on a network resource identifier determined by the client computing system based on the data encoded in the machine-readable data block in the packing list, wherein the request based on the network resource identifier includes a second access token that is based on the first access token;
• in response to the received request based on the network resource identifier, transmitting to the client computing system a uniform resource identifier;
• receiving from the client computing system a request to access the shipment information, wherein the request to access the shipment information uses the uniform resource identifier and includes the access token from the data encoded in the bar code in the packing list;
• determining, based on the first access token, whether to allow access to the shipment information;
• and
• allowing access to the shipment information only when it is determined to allow access to the shipment information;
• and
• performing, based on the second access token, a limited number of translations of the network resource identifier into the uniform resource identifier.

A non-transitory computer-readable medium including contents that are configured, when executed, to cause a computing system to perform a method for securing access to shipment information, the method comprising:

• restricting and redirecting access to shipment information, the access based on data encoded in a bar code in a packing list, the data including a first access token, by:
• receiving a request from a shipment preparation computing system and based on a network resource identifier determined by the shipment preparation computing system based on the data encoded in the bar code in the packing list, wherein the request based on the network resource identifier includes a second access token;
• in response to the received request based on the network resource identifier, transmitting to the shipment preparation computing system a uniform resource identifier;
• receiving from the shipment preparation computing system a request to access the shipment information, wherein the request to access the shipment information uses the uniform resource identifier and includes the access token from the data encoded in the bar code in the packing list;
• determining access information, based at least in part on the request to access the shipment information;
• determining, based on the access information, whether to allow access to the shipment information;
• allowing access to the shipment information only when it is determined to allow access to the shipment information;
• and
• performing, based on the second access token, a limited number of translations of the network resource identifier into the uniform resource identifier.
