Lightweight Selective Disclosure for Verifiable Documents on Blockchain
To achieve lightweight selective disclosure for protecting privacy of
document holders, we propose an XML format for documents that can hide
arbitrary elements using a cryptographic hash function and salts, which allows
to be partially digitally signed and efficiently verified, as well as a JSON
format that can be converted to such XML. The documents can be efficiently
proven to exist by representing multiple such structures as a Merkle tree and
storing its root in blockchain.
We show that our proposal has advantages over known methods that represent
the document itself as a Merkle tree and partially hide it.Comment: 8 pages, 3 figures, 1 table. Submitted to ICT Expres
Towards Application Portability on Blockchains
We discuss the issue of what we call {\em incentive mismatch}, a fundamental
problem with public blockchains supported by economic incentives. This is an
open problem, but one potential solution is to make application portable.
Portability is desirable for applications on private blockchains. Then, we
present examples of middleware designs that enable application portability and,
in particular, support migration between blockchains.Comment: Proc. IEEE HotICN 2018, August 201
Hirota bilinear forms with 2-toroidal symmetry
In this note, we compute Hirota bilinear forms arising from both homogeneous

Protective Effects of Bacterial Immunostimulants, OK-432 and LC 9018 on Pseudomonas aeruginosa Infection in Tumor-Bearing Mice
Survival rates among sarcoma-180 bearing mice against Pseudomonas aeruginosa infection were fewer than those among normal mice. However, the mortality of tumorbearing mice against the infection was reduced in case of administration of bacterial immunostimulants such as OK-432 and LC 9018
