Abstract

Claims (49)

1. A method comprising:

receiving, by a computing device, a plurality of file segments of a file, the plurality of file segments being received individually by the computing device;

scanning, by the computing device, a first file segment of the file to identify the presence of malware within the file segment;

encrypting, by the computing device, the first file segment of the file to create an encrypted file segment in response to identification by the scan of the first file segment that malware is absent from the first file segment;

sending, by the computing device, the encrypted file segment of the file to another computing device before a second file segment of the file is received by the computing device;

receiving the second file segment of the file by the computing device;

encrypting the second file segment of the file to create an encrypted second file segment of the file;

sending the encrypted second file segment of the file to the another computing device to download the encrypted second file segment of the file before a third file segment of the file is received by the computing device;

scanning the second file segment of the file to determine validity of the second file segment of the file, wherein validity is indicative of an absence of the malware; and

if the second file segment of the file is determined to be valid, sending the another computing device information to decrypt the encrypted second file segment of the file, and

if the second file segment of the file is determined to be invalid, preventing the information from being sent to the another computing device to decrypt the encrypted second file segment of the file.

2. The method of claim 1 further comprising:

determining that the file is valid; and

determining that the file is completely downloaded to the another computing device.

3. The method of claim 2 further comprising sending the another computing device information to decrypt at least the encrypted file segment of the file in response to determining that each segment of the file is valid and in response to determining that the each segment of the file is completely downloaded to the another computing device.

4. The method of claim 3 wherein the information to decrypt the encrypted file segment of the file is different than the information to decrypt the encrypted second file segment of the file.

5. A computer program product residing on a non-transitory computer readable storage medium having a plurality of instructions stored thereon which, when executed by one or more processors, causes the one or more processors to perform operations comprising:

receiving, by a computing device, a plurality of file segments of a file, the plurality of file segments being received individually by the computing device;

scanning, by the computing device, a first file segment of the file to identify the presence of malware within the file segment;

encrypting, by the computing device, the first file segment of the file to create an encrypted file segment in response to identification by the scan of the first file segment that malware is absent from the first file segment;

sending, by the computing device, the encrypted file segment of the file to another computing device before a second file segment of the file is received by the computing device;

receiving the second file segment of the file by the computing device;

encrypting the second file segment of the file to create an encrypted second file segment of the file;

sending the encrypted second file segment of the file to the another computing device to download the encrypted second file segment of the file before a third file segment of the file is received by the computing device;

scanning the second file segment of the file to determine validity of the second file segment of the file, wherein validity is indicative of an absence of the malware; and

if the second file segment of the file is determined to be valid, sending the another computing device information to decrypt the encrypted second file segment of the file, and

if the second file segment of the file is determined to be invalid, preventing the information from being sent to the another computing device to decrypt the encrypted second file segment of the file.

6. The computer program product of claim 5 wherein the operations further comprise:

determining that the file is valid; and

determining that the file is completely downloaded to the another computing device.

7. The computer program product of claim 6 wherein the operations further comprise sending the another computing device information to decrypt at least the encrypted file segment of the file in response to determining that each segment of the file is valid and in response to determining that the each segment of the file is completely downloaded to the another computing device.

8. The computer program product of claim 7 wherein the information to decrypt the encrypted file segment of the file is different than the information to decrypt the encrypted second file segment of the file.

9. A computing system comprising:

a memory; and

a processor coupled to the memory, and configured to:

receive, by a computing device, a plurality of file segments of a file, the plurality of file segments being received individually by the computing device;

scan, by the computing device, a first file segment of the file to identify the presence of malware within the file segment;

encrypt, by the computing device, the first file segment of the file to create an encrypted file segment in response to identification by the scan of the first file segment that malware is absent from the first file segment;

determine that the file is valid;

send, by the computing device, the encrypted file segment of the file to another computing device before a second file segment of the file is received by the computing device in response to determining that the file is valid;

receive the second file segment of the file by the computing device;

encrypt the second file segment of the file to create an encrypted second file segment of the file;

send the encrypted second file segment of the file to the another computing device to download the encrypted second file segment of the file before a third file segment of the file is received by the computing device;

scan the second file segment of the file to determine validity of the second file segment of the file, wherein validity is indicative of an absence of the malware; and

if the second file segment of the file is determined to be valid, send the another computing device information to decrypt the encrypted second file segment of the file, and

if the second file segment of the file is determined to be invalid, prevent the information from being sent to the another computing device to decrypt the encrypted second file segment of the file.

10. The computing system of claim 9 wherein the processor is further configured to determine that the file is completely downloaded to the another computing device.

11. The computing system of claim 10 wherein the processor is further configured to send the another computing device information to decrypt at least the encrypted file segment of the file in response to determining that each segment of the file is valid and in response to determining that the each segment of the file is completely downloaded to the another computing device.

12. The computing system of claim 11 wherein the information to decrypt the encrypted file segment of the file is different than the information to decrypt the encrypted second file segment of the file.
