What does it mean?

1. The Message

{md5 => 81ad00cbd9c2a4f796aac6af46b22b38, owner => BTC:12nMSVCRsmsi7AX3TujjaRvLZJyUQT97oW, inputtx => 36c4a88f58f632cc405129792990b4b6f855d6df61af510151baae331af6e566, previousowner => BTC:1HZwkjkeaoZfTSaJxDw6aKkxp45agDiEzN, idop => EL1}

transfers the ownerhip of the asset with md5

81ad00cbd9c2a4f796aac6af46b22b38

from the owner

BTC:1HZwkjkeaoZfTSaJxDw6aKkxp45agDiEzN

to the owner

BTC:12nMSVCRsmsi7AX3TujjaRvLZJyUQT97oW

2. This Message is signed by the Previous Owner with the private key corresponding to

BTC:1HZwkjkeaoZfTSaJxDw6aKkxp45agDiEzN

because only the Previous Owner can transfer the asset to a New Owner
3. Everyone can check the Previous Owner Sign

GxqddTi1poh31tDKLm7bO+Na5NBhaUStSIUdwDjFtdTKxibFMdfWHef6Usz1VX0cmjVngI+v2P2iXl4b2FcdDME=

against the Message and the address

BTC:1HZwkjkeaoZfTSaJxDw6aKkxp45agDiEzN

4. Then the previous owner sign is appended to the message obtaining the new message

{{md5 => 81ad00cbd9c2a4f796aac6af46b22b38, owner => BTC:12nMSVCRsmsi7AX3TujjaRvLZJyUQT97oW, inputtx => 36c4a88f58f632cc405129792990b4b6f855d6df61af510151baae331af6e566, previousowner => BTC:1HZwkjkeaoZfTSaJxDw6aKkxp45agDiEzN, idop => EL1}, prevownersign => GxqddTi1poh31tDKLm7bO+Na5NBhaUStSIUdwDjFtdTKxibFMdfWHef6Usz1VX0cmjVngI+v2P2iXl4b2FcdDME=}

5.This new message is signed By Bytestamp with the private key corresponding to the DTC address D8GafEsbyssg4TQN71KTbd8QdRg846MxCQ , that is on ByteStamp Web Site and also saved in the Datacoin Blockchain in transaction 78c8b327930ec9ec4e280801e2ebba190add5bcbeca295dba9992d5e2cb455bb
6. Then the Bytestamp sign

IPSPrd9WuM+RPPkeDbVx30B14lAGNIoXv65C8shd8rNf4QFSI2+knprvA+XyGDhUZFknbxxEZlyXEDEm1aIaHEM=

is appended to the message togheter with the Hash of the Previous Transaction containing a data Asset:

0ec93ed39fc999e40a53cd666003db24
7.So we have a new message

{{{{md5 => 81ad00cbd9c2a4f796aac6af46b22b38, owner => BTC:12nMSVCRsmsi7AX3TujjaRvLZJyUQT97oW, inputtx => 36c4a88f58f632cc405129792990b4b6f855d6df61af510151baae331af6e566, previousowner => BTC:1HZwkjkeaoZfTSaJxDw6aKkxp45agDiEzN, idop => EL1}, prevownersign => GxqddTi1poh31tDKLm7bO+Na5NBhaUStSIUdwDjFtdTKxibFMdfWHef6Usz1VX0cmjVngI+v2P2iXl4b2FcdDME=}, bytestampsign => IPSPrd9WuM+RPPkeDbVx30B14lAGNIoXv65C8shd8rNf4QFSI2+knprvA+XyGDhUZFknbxxEZlyXEDEm1aIaHEM=}, prevhash => 0ec93ed39fc999e40a53cd666003db24}

on which is calculated an hash, just as a blockchain works (hashcash)
8. This hash

d7aa7d1add6d95d7e44ca444a57dd2ff

is appended to the Message and we have the final Message

ASSET:{{{{{md5 => 81ad00cbd9c2a4f796aac6af46b22b38, owner => BTC:12nMSVCRsmsi7AX3TujjaRvLZJyUQT97oW, inputtx => 36c4a88f58f632cc405129792990b4b6f855d6df61af510151baae331af6e566, previousowner => BTC:1HZwkjkeaoZfTSaJxDw6aKkxp45agDiEzN, idop => EL1}, prevownersign => GxqddTi1poh31tDKLm7bO+Na5NBhaUStSIUdwDjFtdTKxibFMdfWHef6Usz1VX0cmjVngI+v2P2iXl4b2FcdDME=}, bytestampsign => IPSPrd9WuM+RPPkeDbVx30B14lAGNIoXv65C8shd8rNf4QFSI2+knprvA+XyGDhUZFknbxxEZlyXEDEm1aIaHEM=}, prevhash => 0ec93ed39fc999e40a53cd666003db24}, hash => d7aa7d1add6d95d7e44ca444a57dd2ff}

with the initial tag

ASSET:

which identifies the data as an Asset transaction
9. This final Message is stored in the Datacoin BlockChain, so nobody can change an ownership transfer once it happened.
