Abstract

A computer-implemented method includes identifying a plurality of protected pieces from a conversation. The computer-implemented method further includes generating one or more confidence scores for each protected piece, wherein a confidence score is a degree of associativity between a protected piece and a type of sensitive information. The computer-implemented method further includes determining that the protected piece is associated with the type of sensitive information. The computer-implemented method further includes determining a type of protection action for each protected piece in the plurality of protected pieces. The computer-implemented method further includes performing the type of protection action for each protected piece in the plurality of protected pieces to form a modified conversation that is devoid of the sensitive information. A corresponding computer system and computer program product are also disclosed.

First claim

What is claimed is:

1. A computer-implemented method comprising:
identifying a first protected piece from a conversation, wherein the first protected piece corresponds to a portion of the conversation that includes sensitive information;
selecting, from a plurality of types of protection actions, a first type of protection action for the first protected piece, wherein a type of sensitive information associated with the first protected piece and a type of medium in which the protected piece is stored indicates from which of the plurality of types of protection actions to select; and
performing the first type of protection action on the first protected piece to form a modified conversation, wherein the modified conversation is devoid of the sensitive information.

2. The computer-implemented method of claim 1 , further comprising:
requesting additional clarifying information about the first protected piece based on a confidence score associated with the first protected piece falling below a given threshold level;
adjusting the confidence score, in response to receiving the additional clarifying information, to form an adjusted confidence score; and
determining that the first protected piece is associated with the first type of sensitive information based on the adjusted confidence score exceeding the given threshold level.

3. The computer-implemented method of claim 1 , further comprising:
identifying a first portion of the conversation corresponding to the first protected piece;
identifying a second portion of the conversation corresponding to a second protected piece; and
determining that the first portion corresponding to the first protected piece and the second portion corresponding to the second protected piece overlap.

4. The computer-implemented method of claim 3 , further comprising determining a conflicting overlap based, at least in part, on:
identifying the first type of protection action for the first protected piece;
identifying a second type of protection action for the second protected piece; and
determining that the first type of protection action and the second type of protection action are incompatible.

5. The computer-implemented method of claim 4 , further comprising resolving the conflicting overlap based on:
determining that a first confidence score corresponding to the first protected piece is higher than a second confidence score corresponding to the second protected piece; and
performing the first protection action for the first protected piece and the second protected piece based on the first protected piece having a higher confidence score.

6. The computer-implemented method of claim 4 , further comprising resolving the conflicting overlap based on:
determining that a first hierarchical position corresponding to the first type of protection action is higher than a second hierarchical position corresponding to the second type of protection action; and
performing the first type of protection action for the first protected piece and the second protected piece based on the first protected piece having a higher hierarchical position.

7. The computer-implemented method of claim 4 , further comprising resolving the conflicting overlap based on:
requesting additional clarifying information about the conflicting overlap; and
performing a same type of protection action for the first protected piece and the second protected piece based on the additional clarifying information.

8. A computer program product, the computer program product comprising one or more computer readable storage media and program instructions stored on the one or more computer readable storage media, the program instructions comprising instructions to:
identify a first protected piece from a conversation, wherein the first protected piece corresponds to a portion of the conversation that includes sensitive information;
select, from a plurality of types of protection actions, a first type of protection action for the first protected piece, wherein a type of sensitive information associated with the first protected piece and a type of medium in which the protected piece is stored indicates from which of the plurality of types of protection actions to select; and
perform the first type of protection action on the first protected piece to form a modified conversation, wherein the modified conversation is devoid of the sensitive information.

9. The computer program product of claim 8 , further comprising program instructions to:
request additional clarifying information about the first protected piece based on a confidence score associated with the first protected piece falling below a given threshold level;
adjust the confidence score, in response to receiving the additional clarifying information, to form an adjusted confidence score; and
determine that the first protected piece is associated with the first type of sensitive information based on the adjusted confidence score exceeding the given threshold level.

10. The computer program product of claim 8 , further comprising program instructions to:
identify a first portion of the conversation corresponding to the first protected piece;
identify a second portion of the conversation corresponding to a second protected piece; and
determining that the first portion corresponding to the first protected piece and the second portion corresponding to the second protected piece overlap.

11. The computer program product of claim 10 , further comprising determining a conflicting overlap based, at least in part, on program instructions to:
identify the first type of protection action for the first protected piece;
identify a second type of protection action for the second protected piece; and
determine that the first type of protection action and the second type of protection action are incompatible.

12. The computer program product of claim 11 , further comprising resolving the conflicting overlap based on program instructions to:
identify a highest confidence score between a first confidence score corresponding to the first protected piece and a second confidence score corresponding to the second protected piece; and
perform a protection action corresponding to a protected piece with the highest confidence score for each of the first protected piece and the second protected piece.

13. The computer program product of claim 11 , further comprising resolving the conflicting overlap based on program instructions to:
identify a highest hierarchical position between a first protection action corresponding to the first protected piece and a second protection action corresponding to the second protected piece; and
perform a protection action with the highest hierarchical position for each of the first protected piece and the second protected piece.

14. The computer program product of claim 11 , further comprising resolving the conflicting overlap based on program instructions to:
request additional clarifying information about the conflicting overlap; and
perform a same type of protection action for the first protected piece and the second protected piece based on the additional clarifying information.

15. A computer system, comprising:
one or more computer processors;
one or more computer readable storage media;
computer program instructions;
the computer program instructions being stored on the one or more computer readable storage media for execution by the one or more computer processors; and
the computer program instructions comprising instructions to:
identify a first protected piece from a conversation, wherein the first protected p
