Method and system for secure distributed software-service

A network for secure sharing of software applications among a plurality of clients, comprising:

• at least one server configured to provide a cloud hosting a collaboration software module;
• and
• at least one data connection to a software provider configured to:
• receive a request to perform a task from a first client;
• and
• send a set of secure user-defined functions (UDFs) applicable to the task to the cloud, and further end a first identifier of the first client to the cloud, wherein each of the set of secure UDFs is encrypted using an encryption key;
• the collaboration software module being configured to cause a processor of the cloud to:
• store, on the cloud, a cloud's known identifier of the first client prior to provision of the first identifier of the first client to the cloud system, and determine, upon receipt of the first identifier of the first client on the cloud system, that the first identifier matches the cloud's known identifier of the first client;
• apply the set of UDFs to raw data of said first client placed in said cloud to produce requisite information subject to a determination that the first identifier matches the cloud's known identifier of the first client;
• place the requisite information in a memory space of the cloud;
• permit the first client to access the requisite information based on the first identifier;
• receive from said first client a second identifier of a second client, of the plurality of clients;
• receive from said second client said encryption key;
• permit the second client to access the requisite information based on the encryption key and a match of the second identifier to a cloud's known identifier of the second client.

A non-transitory computer-readable medium comprising program code that, when executed on one or more devices on a network including a server including a processor and a memory that is configured to provide a cloud hosting a collaboration software module and including at least one data connection to a software provider, causes the at least one data connection to:

• receive a request to perform a task from a first client;
• and
• send a set of secure user-defined functions (UDFs) applicable to the task to the cloud, and further end a first identifier of the first client to the cloud, wherein each of the set of secure UDFs is encrypted using an encryption key;
• and causes the processor of the server to:
• store, on the cloud, a cloud's known identifier of the first client prior to provision of the first identifier of the first client to the cloud system, and determine, upon receipt of the first identifier of the first client on the cloud system, that the first identifier matches the cloud's known identifier of the first client;
• apply the set of UDFs to raw data of said first client placed in said cloud to produce requisite information subject to a determination that the first identifier matches the cloud's known identifier of the first client;
• place the requisite information in a memory space of the cloud;
• permit the first client to access the requisite information based on the first identifier;
• receive from said first client a second identifier of a second client, of the plurality of clients;
• receive from said second client said encryption key;
• permit the second client to access the requisite information based on the encryption key and a match of the second identifier to a cloud's known identifier of the second client.
