Abstract

Claims (71)

1. A method comprising:

compressing a batch of messages having a message pattern to create a set of compressed messages, the messages including sensor event data;

associating a first batch metadata with the set of compressed messages, the first batch metadata describing how the set of compressed messages is formatted;

applying a security operation to the set of compressed messages to create a set of secured messages;

updating the first batch metadata with security operation information to create a second batch metadata; and

associating the second batch metadata with the set of secured messages;

wherein:

the message pattern for each message in the batch of messages is the same.

2. The method of claim 1 , further comprising:

setting a message buffer for receiving a plurality of messages, the message buffer having an adjustable size; and

generating from the plurality of messages the batch of messages having the message pattern.

3. The method of claim 1 , further comprising:

determining a message pattern;

identifying a set of messages having the message pattern; and

generating the batch of messages from the set of messages.

4. The method of claim 1 , wherein applying the security operation to the set of compressed messages includes:

replacing a data field and an associated value of messages of the set of compressed messages with a token to create a set of tokenized messages; and

applying cryptographic operations to the set of tokenized messages.

5. The method of claim 4 , wherein the token is predefined in a token dictionary.

6. The method of claim 1 , further comprising:

transmitting the set of secured messages and the second batch metadata to an application; and

retrieving a message from the set of secured messages and corresponding third batch metadata.

7. A computer program product comprising a computer readable storage medium having stored thereon:

first program instructions programmed to compress a batch of messages having a message pattern to create a set of compressed messages, the messages including sensor event data;

second program instructions programmed to associate a first batch metadata with the set of compressed messages, the first batch metadata describing how the set of compressed messages is formatted;

third program instructions programmed to apply a security operation to the set of compressed messages to create a set of secured messages;

fourth program instructions programmed to update the first batch metadata with security operation information to create a second batch metadata; and

fifth program instructions programmed to associate the second batch metadata with the set of secured messages;

wherein:

the message pattern for each message in the batch of messages is the same.

8. The computer program product of claim 7 , further comprising:

sixth program instructions programmed to set a message buffer for receiving a plurality of messages, the message buffer having an adjustable size; and

seventh program instructions programmed to generate from the plurality of messages the batch of messages having the message pattern.

9. The computer program product of claim 7 , further comprising:

sixth program instructions programmed to determine a message pattern;

seventh program instructions programmed to identify a set of messages having the message pattern; and

eighth program instructions programmed to generate the batch of messages from the set of messages.

10. The computer program product of claim 7 , wherein the third program instructions programmed to apply the security operation to the set of compressed messages include:

program instructions to replace a data field and an associated value of messages of the set of compressed messages with a token to create a set of tokenized messages; and

program instructions to apply cryptographic operations to the set of tokenized messages.

11. The computer program product of claim 10 , wherein the token is predefined in a token dictionary.

12. The computer program product of claim 7 , further comprising:

sixth program instructions programmed to transmit the set of secured messages and the second batch metadata to an application; and

seventh program instructions programmed to retrieve a message from the set of secured messages and corresponding second batch metadata.

13. A computer system comprising:

a processor set; and

a computer readable storage medium;

wherein:

the processor set is structured, located, connected, and/or programmed to run program instructions stored on the computer readable storage medium; and

the program instructions include:

first program instructions programmed to compress a batch of messages having a message pattern to create a set of compressed messages, the messages including sensor event data;

second program instructions programmed to associate a first batch metadata with the set of compressed messages, the first batch metadata describing how the set of compressed messages is formatted;

third program instructions programmed to apply a security operation to the set of compressed messages to create a set of secured messages;

fourth program instructions programmed to update the first batch metadata with security operation information to create a second batch metadata; and

fifth program instructions programmed to associate the second batch metadata with the set of secured messages;

wherein:

the message pattern for each message in the batch of messages is the same.

14. The computer system of claim 13 , further comprising:

sixth program instructions programmed to set a message buffer for receiving a plurality of messages, the message buffer having an adjustable size; and

seventh program instructions programmed to generate from the plurality of messages the batch of messages having the message pattern.

15. The computer system of claim 13 , further comprising:

sixth program instructions programmed to determine a message pattern;

seventh program instructions programmed to identify a set of messages having the message pattern; and

eighth program instructions programmed to generate the batch of messages from the set of messages.

16. The computer system of claim 13 , wherein the third program instructions programmed to apply the security operation to the set of compressed messages include:

program instructions to replace a data field and an associated value of messages of the set of compressed messages with a token to create a set of tokenized messages; and

program instructions to apply cryptographic operations to the set of tokenized messages.

17. The computer system of claim 16 , wherein the token is predefined in a token dictionary.

18. The computer system of claim 13 , further comprising:

sixth program instructions programmed to transmit the set of secured messages and the second batch metadata to an application; and

seventh program instructions programmed to retrieve a message from the set of secured messages and corresponding second batch metadata.
