Method, system and apparatus for accessing a resource based on data supplied by a local user

A computer-readable medium comprising computer-readable program code which, when interpreted by a computing apparatus, causes the computing apparatus to execute a method, the computer-readable program code comprising:

• first computer-readable program code for causing the computing apparatus to acquire candidate data in association with a request for accessing a resource, said candidate data comprising first and second data;
• second computer-readable program code for causing the computing apparatus to process said first data with a first key in an attempt to effect decryption of said first data, thereby to obtain first processed data;
• third computer-readable program code for causing the computing apparatus to process the second data with a second key in an attempt to effect decryption of said second data, thereby to obtain second processed data;
• and
• fourth computer-readable program code for causing the computing apparatus to grant said request if a pre-determined portion of said first processed data is derivable from said second processed data.

A method of pre-authorizing a user to access a resource, comprising:

• determining a user identifier associated with the user;
• applying a hash function to said user identifier to create a hash value;
• determining a second identifier associated with a group of users pre-authorized to access the resource, said group including said user;
• encrypting the second identifier and at least one of the user identifier and the hash value with an encryption key to produce first data;
• providing said first data and the other of the user identifier and the hash value to said user.

A method, comprising;

• informing a user of a data element indicative of said user being pre-authorized to access a resource to which access is controlled by a gateway entity;
• receiving usage data from said gateway entity, said usage data being indicative of said user accessing said resource via said gateway entity;
• and
• compensating said gateway entity for said user's access to said resource.
